Ken Park (2002)
Claude's father: You can pick your friends but you can't pick your family.
Tate: I killed my grandfather, because he is a cheater who likes to tell war stories, and I killed my grandmother because she's a passive-aggressive bitch who doesn't respect my privacy.
[His grandmother walks into the room]
Tate: No, I'm not hungry. I'm working, and when you come here without knocking, it means that you're acting like a fucking bitch!
