Rob: I did a bad thing
Katie: oh yeah?
Rob: I found something I want. There's a black ninja (motorcycle) at World of Powersports
Rob: and it's really pretty. I want it.
Katie: Are you insane? We have no money.
Rob: Think how much money we would save on gas
Katie: unless the thing can blow you, I'm not interested.
Rob: Why? Is that a position that needs filled?
Katie: It would be if you bought a motorcycle.
