I also believe this song is about internet dating, and that maybe when you don't meet by being face to face, you're less likely to judge someone by outer appearances. I'm thinking this because of the 'She lost her legs in a car crash three years ago/She doesn't get around much' part. Like, she...lost her legs, yeah, and the 'she doesnt get around much' bit could refer to actually moving, or to - I'm thinking - making relationships, because some people can have a hard time accepting that sort of thing enough to make a real relationship and all.
