Origins and Causes of the Cold War

————————————————- Why the iron curtain descended: origins and causes of the cold war ROHAN SINGH SEPTEMBER 2012 Name of University: The West Bengal National University of Juridical Sciences Subject:Political Science Date of Submission:1st October, 2012. â€Å"Why the Iron curtain descended†: A study into the origins and causes of the cold war INTRODUCTION On April 16, 1947, Bernard Baruch, former advisor to former U. S.Presidents, Harry Truman and Woodrow Wilson came up with the term ‘Cold War’ to describe the breakdown in relations between the two superpowers at the time-the United States of America and the Soviet Union. Historian Walter Lippman, his friend used it in the New York herald Tribune-which marked it’s introduction in popular media. This mutual antagonism between the two nations manifested itself, not in all-out war but in attacks thro ugh economic sanctions, proxy wars, the building of alliances propaganda warfare, enmeshed in an overarching principle of non-cooperation.In this context, before delving into the causes, which this essay seeks to do, it is imperative to note that the fact that the two superpowers fought on the same side during World War II was nothing but a ‘marriage of convenience,’ where they were united against the common enemy rather than on grounds of a common cause. The suspicions, ensuing due to the differences in ideology and motives on the global scale had not been occluded by any means, merely erased for the time being. ‘THE BREAKDOWN OF ‘THE MARRIAGE OF CONVENIENCE’To fully understand the origins of the Cold War and the breakdown in relations,it is necessary for us to consider the Yalta, Potsdam and Tehran conferences that occurred towards the dying stages of the Second World War. The Tehran Conference held in 1943 was attended by Roosevelt, Churchill and S talin and even though, the leaders went to Tehran with different goals in mind, the quintessential objective, which was to open a second front against Germany, was achieved. The ‘big three’ met again in Yalta in February, 1945.Relations again seemed cordial and the three leaders agreed on various key points, such as the formation of the United Nations, punishment of the Nazi war criminals, the division of Germany and Berlin into four zones, the holding of free elections in Eastern Europe. Yet, there were perilous signs foreshadowing the origin of the Cold War as the three disagreed about what was to be done about Poland. Stalin’s demand that the Soviet Union should be given all land east of the Oder-Neisse Line was not taken too favorably by the other two leaders.When they met at Potsdam again in July 1945, relations were not so amicable. Various changes had taken place in the international stage since Yalta. Firstly, the Soviet Union’s Red Army had taken control of the Baltic States under the pretext of liberating them. Secondly, both the United States and Great Britain had different leaders representing them. Attlee replaced Churchill and Truman replaced Roosevelt. Both the new leaders were far more suspicious of Stalin and his ‘red agenda’ than their predecessors had been. Fourthly, the Americans had already tested an atom bomb on July 16, 1945.While Stalin was informed of this development at the conference, the motive behind the Manhatten Project was a manifestation of the suspicion the leaders harbored towards the Communist as they wanted to ensure that Japan was invaded by them and not the Soviet Union. Truman also disagreed with Stalin’s request for a ‘Soviet sphere of influence’ and kept on pressing for free elections in the liberated states of Eastern Europe, which Stalin objected to on grounds of Soviet security. The expansion of the USSR east of the Oder-Neisse line in Poland remained a top ic of dispute.The setting up of a government in Poland that recognized all three powers, termed as a ‘Provisional Government of National Unity’ (also known as the Lublin Poles), which effectively rendered the Polish government in exile a thing of the past was another source of conflict. WHO WAS TO BLAME FOR THE COLD WAR? : USA, USSR OR SIMPLE IDEOLOGY? Now, we come to the three schools of thought on the origins of the Cold War. The traditionalists, led by the eminent historian George Kennan believe that the Stalin and USSR were to blame, owing to their agenda, which involved expanding Communism and establishing control over all the Eastern-European tates. In the 1960s and 1970s, Russian historians, who propounded the revisionist view believed that the United States were to blame for the war as the leaders had become paranoid about Communist aggression, whereas Stalin’s motives were purely defensive and the establishment of his ‘sphere of influence’ i n Eastern Europe was justified on grounds that USSR had suffered grave economic losses during the war and it seemed prudent to ensure that neighboring states weren’t hostile.This view became more popular during the 1960s and 1970s as the inherent paranoia regarding both the external and internal Communist Threat, better known as ‘The Red Scare,’ propounded by the Senator Joseph McCarthysubsided in the United States and people become exceptionally critical of American foreign policywith the emergence of the Vietnam War. The third view, which is accepted by most historians across the globe, including this author is the post-revisionist view, which says that it would be unfair to blame the origin of the Cold War on any of the sides without placing equal blame on the other.Furthermore, to fully understand, the causes behind the Cold War, we need to consider a multitude of factors. Firstly, the World War II had a detrimental impact on the economies of both Britain and France and neither of them were the superpowers they had once been. Thus, the USA and the USSR were now the remaining superpowers, two superpowers, which had starkly different and almost contradictory ideologies on government and economics. The Soviet system of government was a Communist one based on the Marxist principles of equality and the welfare state, which involved central planning at the expense of individual freedom.On the other hand, the United States was a capitalist democracy, which espouses the ownership of private wealth, embedded in the pursuit of profits, at the expense of economic disparity. This also led to a breakdown in communication. Every act was construed by the other superpower to be a propaganda move to thwart the other. The Truman Doctrine, which vowed to provide military aid to European states from internal or external aggression and the Marshall Plan, largely responsible for the economic rebuilding of Europe were interpreted, perhaps rightly, by the Sovi et Union as means of spreading USA’s capitalist agenda.Stalin responded to the ‘capitalist expansionist’ agenda of the Marshall Plan by setting up the Council for Mutual Economic Assistance (COMECON) to economically aid the members of the Eastern Block. ‘ACTION AND REACTION:COLD WAR CONFLICTS FROM 1945-1960 Each superpower wanted to spread their specific ideology and contain the other’s, which resulted in a number of propaganda measures, alliancesand proxy wars. The first major cold war conflict was the Berlin blockade and airlift of 1948-49.Stalin cut of all transport links to West Berlin, which was under Allied Control, thus cutting of all food supplies to the city. Truman ordered an airlift with food supplies through B-52 bombers, thus ensuring that the population and autonomy of the zone were kept alive. In 1949, Stalin called of the blockade. The ‘iron curtain’-which was a symbol of both ideological and physical division between Eas tern and Western Europe became permanent and the arms race started to pick up pace.The western nations were convinced of what a potential threat the Soviets could be, which prompted the USA to supplement its military deployment with political affiliations by signing the North Atlantic Treaty Organization in April, 1949, emphasizing the principle of collective self-defense. This, along with the rearmament of The Federal Republic of Germany (West Germany, which was in the Allied Zone) was met with the creation of the Warsaw Pact in 1955. The Soviets also set up a Communist Information Bureau (Cominform), which served as a forum that gathered all communist Eastern Bloc nations.Throughout the 1950s, both countries continued to build up their military arsenal- of both conventional and nuclear weapons. This form of action and reaction due to high levels of suspicion and hostility towards the other played a key role in laying the foundations of the Cold War that ensued. The final Cold War Conflict of the 1950s which laid down the foundation for the tension that would exist in a divided Europe for the next forty years was the Berlin Crisis, which ensued from 1958-61.In 1961, The Soviet Union constructed a wall between east and West Germany in the heart of Berlin. Khrushchev claimed that it was an attempt to curb the expansion of western influence of fascist attempting to influence the mindset of the people of East Germany through brainwashing and coercion. However, most historians believe that it was simply an attempt to curb the exodus of many immigrants (a number that has been pegged at 3. 5 million before the construction of The Wall) to West Germany, which was doing much better economically.Throughout the Cold War, the war was a physical representation of the divide across the iron curtain and an emblem of the conflicts that it represented. CONCLUSION: THE END OF THE COLD WAR AND THE BEGINNING OF A NEW WORLD ORDER The years 1945-1960 laid down the foundations for the period of international and diplomatic tensions that would ensue between the two superpowers. While, all-out- war- never broke out, the two countries’ policies of containment and brinksmanship brought them close to it on many occasions, such as during the Cuban Missile Crisis of 1962.Of course, the Cuban Missile crisis also helped in improving communication ties and kickstarted the process of arms limitation by the setting up of measures such as the Partial test ban treaty in 1963 and the Moscow-Washington ‘hotline. ’ The period 1969-79 saw a thaw in relations between the two superpowers- a period known as ‘detente’, which ended with the Soviet invasion of Afghanistan in 1979. The end of the Cold War, which was marked by the fall of the berlin Wall in 1989 and the dissolution of the Soviet Union in 1991 led to a ‘new world’ order.In this new era, there has generally been a decrease in inter-state conflicts but other threats to intern ational piece such as conflicts of ethnicity, religion, militancy and terrorism are still rampant. Communal tensions in regions such as Sudan, Somalia and the Congo are latest epitomes of this form of conflict and to truly establish a framework of international piece it will be imperative for national governments, in conjunction with the United Nations to make addressing such issues a priority.

The United States A Growing Problem With Women - 1553 Words

The United States has a growing problem with women in the criminal justice system. There has been a dramatic increase of women since the 1980’s. In addition, the increase of women has brought mothers into the equation. Pregnant mothers who are allowed to keep their newborn while incarcerated has been theorized to have many positive results. Including a higher chance of a positive reentry, allow bonding time between the mother and her child, and easing the pain of their incarceration. Laws vary from state to state, making it hard for parents in prison to get visitation time. The main focus will is that these rights should be given to all parents within the United States prison system. Granting mothers with newborns and other inmates’†¦show more content†¦In 2010 there was more than a million women in the criminal justice system, which has breads many problems within the criminal justice system. The rate women are incarcerated varies throughout the nation in each state. Nationally in 2010, 67 out of every 100,000 women were in prison. (Guerino, P., Harrison, P.M., Sabol, W. (2011). That being the average number for most states, but it has been found to higher in others. Guerino (2010) also found that in Oklahoma had incarcerated more women per capita in any other state with 130 out of 100,000 women in prison, with Maine having the lowest rate of any state incarceration at 21 out of 100,000. Including women that are in local jails, the number increases to 245,000 women that are now incarcerated. Indeed, the United States holds the first spot in leading the world in producing prisoners. Since there has been the increase of women in prison, brings the fact that some of these women are also mothers. In some cases these mothers are pregnant during the time of their incarceration. 1 in 25 women in state prisons and 1 in 33 federal prisons are pregnant when admitted to prison, Maruschak, L. (2008). There are laws in place that allow for the mothers to keep their new born for a period of time while she is incarcerated. Mothers that are incarcerated with children creates many negative effects on the children, their families, and even society. In a study by Anne

She did prefer to wear clothing that would not be seen as â€Å"girly,† such as dresses. Daphne also had a strong preference for her playmates to be boys. She also describes to her readers, too, that she had more of a knack for softball than any desire to perfect the art of makeup. While I wouldn’t consider this a fantasy, Daphne does mention the desire to be as free as a boy is while riding her bike in the sun topless. Counting all of these things as four out of 5 criteria would indeed give Daphne a diagnosis of GID. How these behaviors come about is what researchers really want to know. Is it a chemical imbalance? Did we not make our children play with the right toys? Was she born this way? These are all questions that parents are asking about their children diagnosed with Gender Identity Disorder. Daphne’s parents, however, were not concerned with how she got to be the way she is, but how can I fix it? It is easy to blame the parents when reading The Last Time I Wore a Dress.

Performance And Specifications Of Power Pumps Engineering Essay Free Essays

Introduction Background: The agencies of pumping is the most of import manner of fluid transportation for 1000s of old ages. Ancient Egyptians used water wheels with hoppers for the motion of vehicle marked with H2O for irrigation intent. In the 3rd century BC ; the Grecian scientist Stisebeos Alexandria invents the reciprocating pump to pump H2O. We will write a custom essay sample on Performance And Specifications Of Power Pumps Engineering Essay or any similar topic only for you Order Now The about the same clip discovered the Grecian mathematician Archimedes the prison guard pump, called the composit of mandolins with a coiling traveling on inside the cylinder. Till that clip the there was no much development occurs until the late 17th century, where the Gallic adventurer Denis invent a pump with consecutive blades. Then the British adventurer John Oblad invents the centrifugal pump with curving blades in 1851. Thereafter, the first usage of compressors with axial-flow turbo jet engines where found in the mid-fortiess of the 20th century AD. Reciprocating Pump Positive supplanting pumps are that type of machines which is common for applications that require a really high Pressures and comparatively low flow. In this machine, the liquid flows into a contained infinite, such as a cylinder, speculator, or rotor. Then a traveling Piston forces the liquid out of the cylinder, increasing the force per unit area. The usage of positive supplanting pumps is common in applications that require high discharge force per unit area and comparatively low flow. The discharge force per unit area generated by a positive supplanting pump is – in theory – space. If the pump is dead headed, the force per unit area generated will increase until either a pump portion fails or the driver stalls from deficiency of power. The Reciprocating Pump – besides known as Power Pump- is one type from the Positive Displacement Pump. In his book, Pollak illustrates that the Reciprocating pump has a random-access memory, speculator, Piston or other cylindrical component working backwards and forwards within a cylinder or pump barrel ; this gesture is normally delivered from a grouch go arounding unvarying velocity, and linking rod. Automatic valve control the flow of liquid into the cylinder, and out once more. A Piston or a speculator moves back and Forth in an enclosed cylinder. A reciprocating pump besides has a power terminal and a liquid terminal. Most piston pumps are individual playing ; plunger pumps are dual moving. The diameter of the Piston, the length of the Piston shot and the speed of the Walter pistons determine the pump capacity. See fig Power Pumps: As mentioned by Igor Karassik in his book that the power pump does non develop force per unit area ; it merely produces a flow of fluid. The downstream procedure or shrieking system produces a opposition to this flow, thereby bring forthing force per unit area in the piping system and dispatch part of the pump. The flow fluctuates at a rate proportional to the pump velocity and figure of cylinders. The amplitude of the fluctuations is a map of the figure of cylinders. Karassik added that greater the figure of cylinders, the lower the amplitude of the flow fluctuations at a specific revolutions per minute. It is ever possible for the power pump to bring forth different capacity as they are capable of operating over a broad scope of velocities. Each pump has maximum suction and discharge force per unit area limits that ; when combined with its maximal velocity, find the pump ‘s power evaluation. The pump can be applied to power conditions that are less than its maximal evaluation but at a little lessening in mechanical efficiency Operating Principles: In his paper, Samuel explains the pump operation as follows ; the reciprocating pump uses a crankshaft-connecting rod mechanism. The crankshaft-connecting rod mechanism converts the rotary motion of the crankshaft to a reciprocating additive motion of Pistons. The Piston motion creates volume alterations. As a pit opens when a Piston retracts, the fluid is admitted through an recess cheque valve. When the Piston reverses, the recess look into valve stopping points, and the pit reduces when the Piston extends. The mercantile establishment look into valve clears and the fluid is forced out by the Piston. Despite that of the fluid being pumped, the discharge volume is fixed for each crankshaft revolution. Pressure is determined by the system flow opposition and pump building. The Speed decrease is so needed for diminishing high velocity from the driver to low pump shaft velocity. Applications for Power pumps are: †¢ Oil well clay pumps †¢ Reverse osmosis charge pumps †¢ Auxiliary boiler provender pumps †¢ Pipeline pumps †¢ Oil field H2O injection pumps †¢ Slurry pumps †¢ Process pumps Performance and specifications: In his paper, David Parker negotiations about the specification illustrating that the quality and measure of information on suction conditions will find the ultimate success or failure of any pump installing. The bulk of pump jobs, start at the suction. There must be a minimal sum of absolute force per unit area available to provide fluid to the pump suction. PD pumps by and large require less absolute force per unit area. Net Positive Inlet Pressure Required ( NPIPR ) , at the pump suction rim, is the evaluation of entire recess losingss within that pump at rated conditions. Unit of measurements are force per unit area footings ; PSI, Kg/cm2, Bar, KPa. These losingss include the unstable clash loss along the internal suction way, the alteration in lift from the suction rim to the enclosed volume, the unstable clash loss of come ining the enclosed volume, and the acceleration to the speed of the enclosed volume. For any given size, NPIPR will increase with increased viscousness or fl ow ( increased flow = increased velocity ) . Volumes of gas are normally specified comparative to standard temperature and force per unit area ( STP ) of 680F and atmospheric force per unit area ; 14.7 psia ; 200C, 1.034 Kg/cm2 absolute. By stipulating the standard volume of gas and stipulating the suction force per unit area and temperature, the volume of gas nowadays at the pump suction can be calculated. This capacity must be added to the liquid capacity in order to size the pump for the needed liquid flow rate. If suction force per unit area is below atmospheric force per unit area, even little sums of entrained gas will spread out in volume necessitating a larger pump. Capacity should be defined for the rated status. If there is an acceptable scope of capacities, the lower limit and maximal acceptable should be stated. This allows pump providers to offer standard merchandises without holding to modify for specific capacity demands. Efficiency: In the reciprocating pump, merely two efficiency losingss need to be considered ; volumetric and Mechanical. Volumetric efficiency loss is provoked by slippage through valves, ratio of liquid chamber volume at terminal of shot to plunger/piston supplanting volume, and liquid squeezability. Mechanical efficiency loss occurs while get the better ofing mechanical clash in bearing and velocity decrease. The overall efficiency of a reciprocating pump unit is by and large above 85 % throughout its full operating scope. However, in the reciprocating pump can run over 90 % because many pumps and decrease units operate at a mechanical efficiency of 98 per centum, and the volumetric efficiency can frequently be above 95 per centum. Viscosity: Viscosity of a fluid is the ratio of shear emphasis to the rate of shear strain. It is a step of its opposition to flux. High viscousness fluids, like gum elastic, adhesives, or molasses, are really immune to forces applied to travel them. Low viscousness fluids, like kerosine or H2O, have really small opposition to coerce. Viscosity is reduced as temperature is increased ; hot fluids flow more readily than cold fluids. Viscosity should ever be given at a specified temperature. Typical units for viscousness are centipoises, centistokes, and SSU. Positive Displacement pumps maintain high efficiencies throughout the viscousness scope. Entrained gasses can be handled in big measures by most Positive Displacement pump designs ; nevertheless care must be taken in stipulating measure of gas entrained and flow required. Positive Displacement pumps are used to keep the changeless flow rate as nozzle force per unit areas change due to choke offing and gnawing. Precise control of fuel add-on rates increases the operators control over burning conditions. This in bend leads to cut down air emanations, a really critical concern in a extremely regulated industry. The reciprocating pump provides a about changeless flow rate over a wider scope of force per unit area ; the centrifugal pump gives unvarying force per unit area over a scope of flow, so it drops dramatically as the flow rate additions. On a reciprocating pump, fluid viscousness has small consequence on the flow rate as the force per unit area increases. However, unstable viscousness has a large impact on the centrifugal pump ‘s force per unit area and flow rate. The efficiency besides drops well. Advantages: Efficiency is rather high even though there are alterations in the needed caput. It can be up to 85 % to 95 % or even more. Merely with high velocity it tends to diminish somewhat. Reciprocating pumps run at much lower operating velocities than centrifugal pumps and therefore is better suited for managing viscose fluid. For a given velocity the flow rate is changeless regardless of caput, the pump is limited merely by the power of the premier mover and the strength of the pump parts. The fluid flow from the reciprocating pump is well high. It is start automatically. No demand to make full the cylinders before get downing. Disadvantages: There are poorer in managing liquids incorporating solids that tend to eat valves and seats. Because of the pulsating flow and force per unit area bead throw the valves they require larger suction force per unit area at the subdivision rim to avoid cavitations. Due to mechanical quivers, the pulsating flow require a particular attending to subdivision and discharge piping design Hovering gesture of the nozzle creates perturbations that travel at velocity of sound from the pump cylinder shrieking system. These perturbations cause the force per unit area degree of the system to fluctuate with regard to clip. It is hard to pump syrupy liquid in the reciprocating pump The cost of bring forthing Piston pumps is high. This is due to the really accurate sizes of the cylinders and Pistons. Besides, the geartrain needed to change over the rotary motion of the thrust motor into a reciprocating action involves excess equipment and cost. Discharge flow problems: Care cost a batch considered with its handiness, because throbing flow and big figure of traveling parts, as the atoms can acquire into the little clearances and cause terrible wear. The Piston pump therefore, should non be used for slurries. The throbing features of the fluid fluxing into and out of power pumps are significantly affected by the figure of Pistons. Discharge flow pulsings are the most critical because of the high energy potency generated when the system opposition reacts with the flow to make force per unit area. Since the magnitude of the discharge pulsing is largely affected by the figure of cylinders, so we can get the better of the pulsing flow by increasing the figure of cylinders. Besides, we can cut down the discontinuity by utilizing an collector at the terminal of the nose which will provides a continues flow.

Analysis Essay Revolution By The Beatles Example For Students

Analysis Essay Revolution By The Beatles Word Count: 645 to this day are one of the most famous and popular rock n roll groups in the world. The Beatles include George Harrison, John Lennon(1940-1980), Paul McCartney, and Richard Starkey(Ringo Starr). All of the Beatles where born and raised in Liverpool, England. John Lennon was considered the leader of the band. George Harrison was the lead guitarist. John Lennon was a song writer, one of the two lead singers, and rhythm guitarist. Paul McCartney was a song writer, one of the two lead singers, and a bassist. Ringo Starr played the drums. John Lennons first band was called the Quarrymen (named after his High School). None of the three Beatles were in this band. Paul joined the group in 1957 and Harrison joined in 1958. They played with bass guitarist Sut Sutcliffe, and Pete Best, a drummer. Sutcliffe left in 1961 and Ringo Starr joined the band. Pete Best was asked to leave the band on April 16, 1962. He was considered the Beatles undisputed sex symbol. The Beatles were discovered on November 9, 1961 by Brian Epstein, a manager of a record store in Liverpool as well as an x British Army soldier. The Beatles first two song were Love Me Do and Please, Please Me.The Beatles starred in two movies, A Hard Days Night, and Help.They also had their own full length cartoon called Yellow Submarine. The movie A Hard Days Night earned 1.3 million dollars in its first week. The Beatles early music was influenced by singers Chuck Berry and Elvis Presley. In November of 1963 the Beatles performed in front of the Queen of England. This was an incredible honor. By the end of 1963 the Beatles were the biggest music group in England. The Beatles came to New York City for the first time in 1964. They were an instant success.A couple of weeks later after their New York appearance, the five best selling records were by the Beatles. They became world famous by the end of 1964. Also in 1964 the song I Want To Hold Your Hand marked the beginning of BEATLEMANIA.The Beatles were unusual because most rock was strong beat with no melody. The Beatles added melody to rock. The Beatles also added strong and meaningful lyrics. John Lennon wrote a book called In His Own Write.The Beatles started a new era of music. They wore their hair long and shaggy. This haircut was known as the Beatles haircut. All across the world people started wearing their hair like the Beatles. John Lennon described the Beatles like this When you said it, it was crawly things, when you read it, it was beat music. The Beatles made their last stage appearance together in 1966. In 1967 the Beatles put together a master piece. The master piece was Sergeant Peppers Lonely Heart Club Band. The Beatles never had a chance to perform Sergeant Peppers Lonely Heart Club Band. Also in 1967 Brian Epstein, the manager of the Beatles, died. Also in 1967 the Beatles directed a movie, Magical Mystery Tour. The movie was about themselves in which they toured the English countryside in search of wonder, fun, and magic. In 1970 the world famous and world loved Beatles separated.Everybody was hoping to see the Beatles come back together. That hope ended when the peace loving John Lennon was killed outside his New York City apartment by 25 year old Mark David Chapman.

Nothing Else Better To Do by David Archuleta free essay sample

For David’s debut album, the Japanese version had a bonus track. â€Å"Save The Day† was released in February 2009. This time around, it’s the same thing. The Japanese version of David’s new album, The Other Side Of Down, does indeed come with a new bonus track. The album will be released in Japan this month, and the new song is called â€Å"Nothing Else Better To Do†. The song was co-written by Archuleta, along with Emanuel Kiriakou (one of the writers of â€Å"Crush†, and the newest single â€Å"Falling Stars†), Andre Merritt, and Lindy Robbins. This song has a funky beat, and almost an island vibe to it. It’s different from the sound we’re used to hearing David sing, but he definitely pulls it off. Although the lyrics are random, if you really listen to them they do make some sense. It’s a love song, but with a twist. We will write a custom essay sample on Nothing Else Better To Do by David Archuleta or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Almost like Train’s â€Å"Hey Soul Sister†. The lyrics to that song are as random as you can get, and yet it’s still sweet and makes sense. Exactly like this song. â€Å"Twenty-five hours every day, I’ve got nothing else better to do†, â€Å"An island of green and blueberry ice, Wish we were there†, â€Å"You’re velvet on a red cupcake, Sound a cello and a violin make†Ã¢â‚¬ ¦ Those are only a few examples of how interesting the lyrics get, and yet if you can picture what David is saying, it becomes really sweet, and not just because of the red cupcake. Basically what he’s saying is that he’s got nothing else better to do than spend time with this person because he likes them so much. They â€Å"put the rings around the moon† as David puts it. It’s pretty clear that David helped pen this song, considering it mentions a lot of music and food (LOL). Another very David song. And that, along with the way he sings it, makes for a very unique song, and I personally love it.
