My 9 yearr old DS has recently been given an email address at his school. As it is a webmail account I have been logging on and checking that the spam blocker is working etc. Today I read a couple of his emails and was shocked to see that he and a friend have been gossiping / bitching about some of the girls in class. Some of the comments are quite unpleasant and I am as it seems very unlike him - he is usually quite a sweet, generous boy and not interested in tittle tattle etc.
What should I do - let him know I have read the emails or just let it pass? I don't think he would really make the same comments in a real (offline) situation.
Any advice?
