Walter: Have you bought Dad a Christmas gift yet?
Susan: No. Have you?
Walter: No, not yet.
Susan: What are you thinking of getting him?
Walter: A new razor, maybe. And you?
Susan: The same.
Walter: Oh. Well, I can get him a CD I guess. It's more interesting than the winter socks he always asks for.
Susan: Whatever you want to do. I may not end up getting him a razor after all. 
Walter wants to buy a new razor for their dad for Christmas. He will buy a CD as Susan wants to buy the same. Susan may change her mind about the gift.
