When I was a young child, I lost a tooth one day at school. I decided to test the Tooth Fairy theory by not telling my parents about the lost tooth - until the next morning, when I went up to my mother crying because the Tooth Fairy didn't leave me any money.
Her excuse was that I didn't look hard enough, and sure enough when I went back ten minutes later there was a dollar bill sitting squarely under my pillow.
