A childhood belief about fairies

I was a suspicious child. I started wondering whether the tooth fairy was real or if it was just my parents putting money under my pillow, so I decided to test it out. The next time a tooth fell out, I didn't tell them, but just put it under my pillow. The next morning, there was no money! That day I pretended to my parents that the tooth had just fallen out, and the morning after that, there was the money under my pillow. Proof that my parents were behind the tooth fairy scam!
