I think it was Sex and the City, anyways. I look at a friend's problems in relationships and dating, contemplate my own contributions to them, and find myself going 'Aw, shit. I'm that guy.' I don't exactly recall context for who or what that guy is, though. But I think it was in Sex and the City. Maybe I'm wrong. But I am pretty sure, regardless, I am that guy.
UPDATE: this post isn't about you. It's about me. Me Me me me me. Hah.
