Katie and Dane just left to go on a date, since it's their one year anniversary. Katie has to work tonight, so a lunch date is pretty much the only choice. Other than, you know, sitting around their respective bedrooms and seething about what an inconsiderate asshole they've each hooked up with.
Luckily, they didn't choose to go that route.
Anyway, while Katie was doing the girl's Secret Date Preparation Ritual, Dane and I were talking about when they first started dating. He said that he came over and I made fun of him, and after they left Katie said, "My mom really likes you! If she didn't, she'd be polite and distant. But if she's already mocking you, that's a good sign!"
So I guess I see where Carrie gets it.
