We have been attempting to correct our 10 year old son's attitude. He argues with EVERYTHING, is so disrespectful, and always has to have the last word. He is also rude to his sister. We have taken away every privilege (electronics, toys, play dates, sports) and even if the rest of the family wants to watch tv, he has to leave the room. This has been going on for 100 days. It's so so frustrating, though, because he doesn't care. He hasn't changed. He comes home from school and either takes a nap or complains or nags his sister. Please tell is what to do. We are exhausted.
