"Put the ax down!"

On his way to bed, my oldest picked up a wooden play ax and headed for his door. Here's the play-by-play:

"What are you doing?"
"Going to bed."
"But why do you have an ax?"
"I want to sleep with it."
"You can't sleep with it."
"Why not?"
"Just go to bed."
- Son proceeds to enter room, ax in hand -
"Put down the ax!"
- THUD - Door closes. Door opens. -
"Good night. I love you."
