"When I grow up..."

Trevor is always asking me if he can be whatever he wants when he grows up. Of course, I say , "Yes! You can be whatever you want to be!" Usually he says he wants to be a golfer and would I please "sign him up" to be a golfer! The other day he said to me, "You know what I'm going to be when I grow up?" I said, "What's that?" He said, "What you are! A grown-up!" (Clever.) Then Gavin said, "You mean you're going to be a grown up that doesn't make money!?" Nice.
