Jill: Tim, we gotta talk. I would have talked last night when I got home. But I could tell you were doing that thing where you pretend you're sleeping so you wouldn't have to talk to me about the opera.
Tim: If you knew I was pretending, why didn't you say something?
Jill: Because you go to that much trouble to tune me out, what would be the point?
Tim: You're right. If the system works, why mess with it?
