Haven't We All?

Me: Tomorrow, we need to get a gift for Girlfriend's birthday party.
Daughter: Oh, this is bad. This is bad, this is bad, this is bad, bad, bad.
Me: What? Why?
Daughter: I have no idea what to get her.
Me: Well... the best gifts to give are usually the ones you would like best yourself.
Daughter: Hm. Well, I've always wanted a water bed.
