Why do I always fall for the ones who aren't good for me?

Iris: Because you're hoping you're wrong. And every time she does something that tells you she's no good, you ignore it. And every time she comes through and suprises you, she wins you over, and you lose that argument with yourself, that she's not for you.

Miles: Exactly, and on top of that there's the old standby, I can't believe a girl like that would actually be with a guy like me.
