Hedging Bets

Yesterday on the way home, Simon announced that his tooth was loose. 

Me: How exciting! Do you know about the Tooth Fairy?
Simon: I don't think she's real. I think it's your parents who put the money under your pillow.

Me: Well, we'll have to wait and see!

Simon: I know. The first night, I'll put my tooth under my pillow and we'll wait to see if she comes. If she comes, great. If there's no treasure under my pillow the next morning, I'll put the tooth under my pillow again, and the second night, you and Daddy can put the treasure under my pillow.
