Years ago, one of my children misbehaved at the dinner table in a rather obnoxious way. As punishment, I told him he would have no dessert and that he would be confined to his bedroom for the rest of the evening.
Crestfallen, my son got down from the table -- and then stopped to ask if it would be acceptable to spend the rest of the evening in my bedroom, rather than his. Taken by surprise, I asked for an explanation.
