My step-son has SCS, bad. But first, let me explain he symptoms. He is 15 and into computers, thus he thinks he knows everything there is to computers, networking, videogames, etc. He is a know-it-all to the point that he has alienated some of his close friends with his jerk behavior. It's really dorky, but he and one of his best friends had a major split up over Minecraft .
Anyways, how do his mother and I address this issue? He had a friend spend the night over the weekend and they got along pretty well but there were moments when his SCS was flaring. He has a lot of trouble sharing things and letting people do things at their pace or letting other people/friends chose an activity. He is huge into videogames and another problem is that he will put his headphones on and act like a total jerk anytime we ask him to do a chore, such as taking out the trash. I know a lot of this is typical teenage behavior, but if I don't figure out how to handle this like an adult I'm afraid I'll handle it like a child and say something hurtful to him.
