This is from my kindergarten journal. I think I was a little bitter because two of my baby teeth had fallen out in kindergarten, but I lost both of them before I could trade them in for cash. I swallowed one and a shag carpet swallowed the other.
Another kid told me that when a similar thing had happened to him, he had just put a note under his pillow explaining the situation, and the tooth fairy had given him his money anyway. When I ran that idea by my mom, she said that kid was wrong.
