I am aware of a father who slpapped his 15 year old daughter in the face with a open hand, not very hard. She has been been consistently defiant of all rules and expectations, verbally abusive to her parents and peers, and is very self-absorbed. She very defiantly told him that she would not do what was demanded of her and used language the neither her nor I would have used (and we're no angels)to someone else, let alone parents. He felt he needed to do that snap her back to the reality that she was not in control.He loves her deeply, but is "over" her complete lack of cooperation and wiilingness to take responsibility for her own actions. I think he feels bad about "having" to do it, but that it was appropriate. What are your thoughts?
