"NO! NO!" the dangling child shrieked as I approached. "You're going to tickle me!"
I stopped short of the monkey bars. I assured the four year old that I would not tickle her, that I merely wanted to spot her. It took many minutes of heated accusations and denials, but finally she let me spot her.
When she got to the other side untickled, I reminded her of her accusations. "Don't you think you owe me an apology?"
She looked confused. "I don't know what that word means," she finally admitted.
