Preteaching stretching for hours

Hi Nicholeen,

I have an 8 year old boy who struggles with condescending behaviors. He is often misunderstood, and struggles with interpersonal relationship because of how he sees the world. He can’t really read the situation of the room and will do annoying things that nobody finds funny thinking that he is funny, when he gets a negative reaction, he will then wallow for days, months, and sometimes years thinking that everyone is out to get him. These behaviors have recently made his Grandpa really upset with him. I started to do preteaches with him to practice the tones in which we talk when he is calm. These preteaches are based on recent situations and he can get so emotional that the preteaches end up with him doing tons of extra chores and with all the questions he asks each preteach can span for two hours. I calmly describe, when he starts to resort to blaming. We are preteaching tones, because when he feels misunderstood, he will often resort to mocking the other person, and he will not own up to any part of his mistakes. I love my son and am willing to spend the time working with him, but how do I shorten these preteaches, to a few minutes, and how do I make it more effective. These preteaches are becoming a place where he is negatively attention seeking.
