E: Look, Mommy--I made you a snowman at school today!
Me: Wow! That's really nice! Can I keep it forever and ever?
E: Why do you want to keep it forever and ever?
Me: So that someday, when you're all grown up, I can look at it and think about when you were a little girl.
E: Oh. So you want to keep it until you're really, really old?
Me: Uh, yes.
E. Okay. But I want it back when you die.
