DS got upset because a boy in his class was being aggressive and nasty to him... This was witnessed by a student TA and she dealt with it. Now I feel bad cos I didn't step in and say something to this boy or another teacher... I just thought it would be best to stay out of it - but now i'm not so sure. This boy is one of the 'challenging children' and IMHO a bit of a bully, what would you have done?
