That is a great idea. How did you get him to do it? We have tried journals, all types of things for my son to try and get out the emotions when he finds things people do and say annoying. Right now, his favorite is to mimic people when he finds them annoying. He does manage to keep it on the quiet side, but they can still hear him, especially when he doesn't do it once. We have told him if he doesn't stop mimicing people, he is going to do it to the wrong person and get punched in the face one day. I will mention this idea to him. He will probably give me a list of reasons on why this will never work for him. Although, I love the idea.
