Me: You know how people around here say...
Spencer: Gah! you were saying how great Utah was today but you hated living there I just think you're never going to be happy.

Spencer: I'm just concerned for you.
Me: Concerned?
(Spencer realizes there is nothing here he can say to justify)
Spencer:... Concerned that you're pissing me off.
