Me: Why?
Z: I don't know. We almost never get dressed up and it's Saturday night and we're going out.
Me: I'm wearing a dress already.
Z: It's a sundress. That's not dressed up.
Me: True.
So we got back about a half hour ago from seeing Batman Begins. In formal wear.
P.S. It's a really good movie.
P.P.S. Everyone else in the theatre (and on the bus getting there and back) was underdressed :-).
