A childhood belief about fairies

i used to believe in the tooth fairy. i did some math and realized that she had to hold about $2 billion on her every night, since she wouldnt have enough time to go back to her house in between visits. and naturally, her first stop of the night would be my house. i decided to catch and rob the fairy, so i hid a small butterfly net under my pillow and pretended to be asleep the night after i had lost a tooth. i must have dozed off because the next thing i knew, there was a faint tinkling noise. i grabbed my net and turned on the light, only to find my dad there, change in hand, trying to find a quarter. im not sure who was more shocked...
