I was playing tooth fairy when my daughter, Marina, suddenly woke up. 

Seeing the money in my hand, she cried out, "I caught you!"

I froze and tried to think of an explanation for why I, instead of the tooth fairy, was putting the money under her pillow but her next words let me off the hook. 

"You put that money back!" she said indignantly.  "The tooth fairy left that for me!"
