(David is gazing admiringly at a pretty blonde girl)

David: *Hi*. I mean, Hi. Uh, look, you probably don't think I should be asking you this. I mean, not knowing you well and all? I mean, you know, I, I, I know you, 'cause everybody knows you. I just don't know you technically. Uh, anyhow. Uh, I don't know what you're doing this weekend, but my mom's leaving town, and she's letting me borrow the car.
(the camera pulls back to show that the girl is standing several dozen feet away and, in fact, is smiling and looking at another boy)
David: *Looks down at the ground, disappointed with himself, but still keeping his tone cheerful* Okey-dokey, so, just give me a call; let me know. Bye!

Big Bob: This behavior must stop at once.
David: But see? That's just the point! It can't stop at once, because it's in you, and you can't stop something that's inside you.
Big Bob: It is not inside me!
David: Oh, sure it is.

George Parker: What happened? One minute, everything's fine... What went wrong?
David: Nothing went wrong. People change.
George Parker: People change?
David: Yeah, people change.
George Parker: Can they change back?
David: I don't know. I think it's harder.

David: I know you miss her, I mean, you told me you did. But maybe it's not just the cooking or the cleaning that you miss. Maybe it's something else. Maybe you can't even describe it. Maybe you only know it when it's gone. Maybe it's like there's a whole piece of you that's missing, too.
