It confirmed how supportive of me my kids are, and also how logical my son was for wondering why in heaven's name anyone could use the mental illness label on us. He couldn't understand it until I reminded him how the world works: people intent on discrediting something will use any means possible irrespective of the weakness of their argumentation. In other words, belief becomes stronger than rationality. He just looked at me and shook his head.
Did I mention I have a very intelligent son?
