My DS(16) came home from school the other Friday and his phone was broken. He told me he threw it which I didn't believe. Then later I got a call from his head of year saying he punched someone in his year so he would be in isolation for the following week (last week). When I asked him why he said he didn't know (thought this was unusual as he isn't violent) but I took his Xbox anyway and said he'd have to pay to repair his phone. Last Tuesday he told my nephew that he didn't throw his phone the boy he punched did and he kept calling him gay etc so son punched him. I phoned the school and they said they'd phone me back but they didn't so I phone on Friday and they said they can't do anything as they don't have any proof that the boy threw it apart from son saying so.
Today son has refused to go to school.
AIBU to think the school should've done something?
