500 Days of Summer is a story where a boy meets a girl, he falls in love with her but she doesn't really love him. The film shows the progression of Tom and Summer's relationship. It starts from their first meeting, when Summer starts working as a secretary where Tom works and progresses until they are casually dating. Summer is visibly hesitant and opposed to relationships, but Tom is too eager to find the perfect girl. The story ultimately shows the end and aftermath of their relationship. At first glance, everyone might think that this is a typical love story in which the film casually progresses towards a happily ever after life. It’s not that kind of fairy tale love story. One of the main reasons Tom and Summer may be interested and attracted to each other is their closeness. They are in the same position, which means they will spend more time with each other and have more interactions. The proximity effect tells us that the more time a person spends with someone and the more interactions they have, the more likely they are to have a closer relationship with us. Tom's immediate and initial attraction to Summer is purely aesthetic. He knows nothing about her except that she has the ideal characteristics associated with Tom's opinion of what is physically attractive. The fact that they have similar appearances could be another facet of the attraction. They both have dark brown hair, are close to each other in height, and have a similar build and body size. Given that studies by Mackinnon, Jordan, and Wilson in 2011 showed that people become close to others with similar characteristics and appearances to them, there's a good chance it's of a... middle of paper. ....as an interest for him. He tries to repeat the action and circumstances to achieve the result and happiness he had in the past. Although they don't end up together at the end of the story, I believe it is the perfect example of the social exchange theory of the time. point of view of the male protagonist. The more social interactions he shares with his love interest, the more he is rewarded, simply because his goal is to have more contact with her and, ideally, make her fall in love with him and live happily ever after.ReferencesAronson , E., Wilson, T.D. and Akert, R.M.
