My son is 15 , is a good kid has good grades or the teachers say what a lovely polite boy is , but yesterday I had a phone call from the school , that he could face expulsion from school for hitting his friend in the face , he instantly regretted and did say sorry , his friend had been saying nasty things to my son about infected eczema on my son face and my sons vitamin d deficiency for over a week now and yesterday my son just snapped , this is out of character for him , it was head of year that phoned and he did say that my son will have to do a statement cause they haven't heard my sons side of what happened, the head of year said that my son is lovely and polite quiet boy . I'm am very concerned about this any advice would be appreciated Thankyou
