Their jokey, flirtatious relationship is based on a shared love of British bands such as the Smiths and on a giggly, conspiratorial feeling of superiority to the silliness and phoniness of everything that surrounds them. But the relationship, which lasts 500 days, is doomed, and Tom plays us scenes from random days, out of narrative order, to illustrate the painful business. The problem seems to be that he believes in love and she doesn't. Or is it that she just doesn't believe in being in love with him?
