I think we forget sometimes, these are kids. KIDS. They look to us, as parents, to set the rules and enforce them. He did not beat his daughter, or simply scream at her. He showed her a consequence of her lack of action. He did the correct thing. She is the child. Her room is under her parent's roof until she turns 18. We have to stop giving our children more power than ourselves. Look at the generation we have now, spoiled entitled kids. Teaching them proper discipline, and giving them proper rewards helps to teach them how to properly behave as adults.
