hooks in my nose

My grandson finally had to go into day care twice a week. We had put it off as long as possible, but now he was six and vocal. We thought he would be safe.
He did not really appreciate being sent there. The “aunty” asked what the rules were.
“No TV, has to do home work and finish his snack.”
He was there for only two hours so this seemed tolerable.
He was however used to being left with his great grandfather earlier.
That meant the old man snoozed and he spent the entire two hours watching “Kick Buttowsky” “Phineas and Ferb” and other strange creatures on television.
“She is very mean” he announced, “she makes me eat my food and do my homework.”
“Too bad,” said my daughter” unless she puts hooks in your nose and hangs you from the ceiling you have to go there.”
Grandson was very silent. A few days later he announced, “she took out two hooks today.”
There was a shocked silence in the room. Feebly, convinced my worst nightmares were confirmed, I said ,“ what did she do with the hooks?”
Grandson looked around the still and silent room room. Lowering his eyes he said, “ she hung a curtain.”
