He wanted to play dentist instead.
In his game of dentist, I have to sit on the couch and hold out my hands. He picks up a wooden spoon and very studiously sets to work running the spoon over each of my fingernails. He makes a low, droning sound as he does. Pausing in the drone between fingernails. Frowns with concentration, then gives me back my hands.
He’s never been to the dentist, Charlie.
