Cover art for Taxi Cab lyrics by Vampire Weekend

Guy meets girl. Guy is a poor hipster, girl is from a rich family. They date a while, but as it's getting serious he starts to take issue with her background and upbringing. He can't see himself dating her because of her background. He finds reasons why it won't work. The relationship eventually ends but as he is reflecting on it, he realizes it was not her fault she who her parents were. He realizes that she was really okay and he liked her. He is admitting that he sort of unconsciously sabotaged his own relationships.

The song has a similar theme to "I think you're a Contra". The protagonist in that song also second-judges a girl and then later realizes he was wrong and that he wanted her.
