My Eyes Clapped Twice

I was reading Charlie and The Chocolate Factory to Ari, before he went to bed, and he stopped me.

"Mommy, when you were talking, my eyes clapped twice."

"What do you mean?" I asked him.

He blinked his eyes slowly, two times.

"See?" He said looking up at me.

"Oh, you mean, you were falling asleep?" I asked

"Yeah, my eyes clapped twice."

I want to live inside his brain.
