He is 13 but has ASD so socially is behind.
He's not settled in well back to school this term but as much as we talk to him he can't get out of his mindset. He is revengeful in thought generally but it has been worse since he had a knife pulled on him at his old school at the end of year 7.
I've always told him he can't control others behaviour but can control his own and when he behaves just as badly in reaction he will get held equally accountable.
Today he went to the park over the road - I can see it from my lounge window. He generally plays nerf guns with children aged about 8-11.
I could hear clanging and so looked out of the window and him and another lad are swinging the swings trying to get them over the bar. There was a few adults there with lots of children aged 4-8 (ish).
I went straight down and called him in and said he's grounded for a week with no tech.
I told him he's been raised better than to think damaging public property is ok and is a fun thing to do.
He looked at me blankly as if he couldn't actually understand what he'd done but I made it clear it's unacceptable and he was fuming yesterday when a boy at school was physical with him and broke his elastic bracelet band and a teacher told him it 'wasn't a big deal' it was broken.
I'm so cross with him - but AIBU to be this annoyed and punish him so severely?
