Wet towel

I got the inkling and I said to my husband " I think son is making some troubles right now..."
He went to check and said "Oh dear son, what have you done?"
"Why did you wet this towel? Do you think you can dry your hands with this towel anymore?"
Son had serious face but then he smiled and answered just "yeah".
So my husband hung the towel back to the hook and said "okay then". :D
