My son is 10 and loves to play FIFA with his friends on xbox. I regularly check his friends list on there and can hear the chats he has with them online. I also make him aware (so I thought) that he does not accept any friend requests other than his friends that I know which he has done up until now. When I checked his account the other day he had accepted a friend request off a name I didn't know and when I asked him he said it's from his new PE teacher at school, he has sent the request to a few of his friends in his class and chats to some of them on there. The "teacher" is actually a 17 year old lad who is working at the school as part of his studies. I have spoken to the head teacher who has assured me that he has spoken to the lad and he understands that he can't behave like that and was just trying to be friendly with the boys.
I'm not completely happy with this lad continuing to teach my son after this though, I don't want to be harsh or accuse him of anything but I just find it hard to understand why he'd want to chat with the boys out of school time. I feel a line has been crossed.
Am I being unreasonable or worrying about nothing? I'm not sure what to do
