I hate that his dad does this. My mum used to do it to me, wouldn't communicate or explain what I'd done wrong. Would just give me the silent treatment and ignore me until she'd got past it. It's emotional bleeping abuse.
Why can't they sit him down, put some boundaries in place and stick to them and make sure he knows what's expected of him. Instead of ignoring him, telling him to get out, filming him and snorting. Yes, he's being a bleeping pain at the moment, he's nearly 16. Put some effort into reining him in a bit, instead of taking every chance to escape. He needs some consistency and some actual bloody parenting!
I'm glad they got reported to SS (if they did), they need someone to show them how to actually parent. Pair of useless, selfish bastards.
