answer:Don’t worry! most of us will eventually grow out of it. In my opinion as long as he isn’t physically hurting anyone, including himself. Try not to engage in these discussions that seem to be carried away. Be a good example of maturity. Try to stay positive and don’t make claims that are a matter-of-fact. In most cases its better not to say something than to say an innocent comment that leads to an argument. For is little brother, maybe teach him to go to another room to play. Also try to arrange family trips (to the library, movies, zoo, hiking, beach, ect) and plan them in advance so there are no excuses not to go. That will help to make positive memories together.
