It's ludicrous.
I could have a conversation with ds1 (14) and he would just lie.
So for example, I asked ds2 to wake dd1 the other morning. He prodded her really hard and made her Yelp. I didn't ask him to do that!!
Ds1 told me ds2 said I had told him to hit dd to wake her up. 
I called ds2 to check and he said no, that wasn't true, he didn't say that.
Ds1 then storms off after saying he never said ds2 told him that. It's risible because his lies are so easy to counter.
He claims stress but he lies all the time. Generates arguments all the time.
It's actually quite remarkable how he manages to draw me into his argument and I need to just not engage with him at all from now on.
He also smashes up stuff like glass bottles and photo frames in the house. Slamming doors. Damaging furniture.
He gets the rage at least once a week and over reacts to everything.
He bunked off school this morning too. The school is furious and will be taking action.
I just can't be arsed anymore. He causes so much distress and damage over nothing. And he's nerved remorseful. Gives this phony apologies which I have to accept in goodwill.
I've spent £££££s on counseling for him. Different Counsellors who've all said what a lovely, intelligent boy he is. I've not been allowed to say what he's like at home because their relationship is confidential.
