I told him he is an idiot once. Once I told him he was crazy. Several times I have told him to **** himself. I don't think I have ever told him he is doing therapy wrong though. Interestingly, the only one of the incidents above that he seemed a bit offended at was the 'idiot' one, and I was using it as a term of endearment. Apparently that is not "normal" in most families.
