My son lost his temper with a girl at school recently and shouted at her and pushed her because she annoyed him. He is on detention and the School have dealt with the situation very well, this is the first time he has behaved like this at school and everyone is shocked as previously he was a model pupil. He will NOT talk about it to anyone and I need to discuss this with him tonight. Should he be punished further ? (eg no TV for a week or being grounded)
