Reth: Hang on a minute, if I'm Brick's girlfriend, but I'm also my girlfriend's boyfriend, does that mean I'm cheating on one of them?
Me: "Yes, you're cheating on both of them!"
Reth: "But I mean, like, I'm Brick's girlfriend, but I'm also my girlfriend's boyfriend, surely that doesn't count, right?"
Brick: "Well, that just makes you a transgender cheater then."
