How concerned should we be that a 15 year old boy has no friends?
This first came up when he was 8 or 9, but we thought he'd grow out of relying on his father as a playmate.
At 13-14, things seemed alright and he always had a gang of guys over, though we did hear of arguments and "he's not my friend" one week and "we're friends again" the next.

Last year he wanted to change school to join the sport (football) program. Unfortunately, he learned, once there, that his grades weren't good enough. Then, he wasn't geting along well with the guys from that football team as they teased him about the team he'd came from.
He wanted to go back to his regular school and was out of school for nearly 4 months (red tape) and is now in yet another school.

My husband attributes his lack of friends to all this moving from school to school.
I've seen how the boy acts sometimes with others and feel there may be more to it than just that. (he tends to be a bit arrogant at times, considerably lazy and gets angry when told anything negative.)
Should we be concerned, or do we let him figure it out for himself?

He is not a solitary person. But he does spend week-end after week-end in his room on the computer, or shuffling around the house looking for something to do with his dad.
What would you do?
Thanks
