The whole tooth

Neil's about to lose his first tooth. It's wiggling and wiggling. He's working it, but not yet. Soon though.

This afternoon he had a serious question for his daddy.

"Does the tooth fairy come every day?"

"He only comes when you lose a tooth."

"Yeah, but can I lose it today? or another day? Will the tooth fairy come on Mondays?"

"The tooth fairy will come any day you lose a tooth and put it under your pillow."

"But Dad," butted in big brother Jack, "Remember that time the tooth fairy didn't come? You said it was his day off."

Oh yeah, that time.

"Union rules have changed since then."
