We had to disturb Daniel the other night as we took to our bed. Aged six, he has never had the power of speech. He needed attention before he could settle finally and cleanly to his slumbers. He surfaced briefly to consciousness as I bent to plant upon his forehead a goodnight kiss. Seeing me he clapped his hands excitedly. I clapped mine.
That's how he learned to clap. By copying me.
So we applauded each other. Then it was back peacefully to sleep.
He claps because I first clapped him.
Very nearly biblical.
