Thank you WhenYouSayNothingAtAll. This has been cathartic to write. I feel I am learning a lot that I had totally forgotten about my behaviour.
How old is his brother?
12
What is the dynamic between them?
They have many shared interests and when things are going well, they are the best brothers—giggles and Pokemon. Generally, DS15 can be quite overbearing towards DS12 - telling him where he went wrong, how he could have done something better, 'edu-instructing' him. DS12 is quite headstrong too but is largely submissive towards DS15. Of late, DS12 doesn't want to walk with DS15 to school.
How is he otherwise? Is he polite/respectful in general?
He finds it very hard to say please or sorry. But he is not overly polite or rude. His teachers think he is a joy and he can be charming and witty if he wants.
He has a tendency to go overboard snap at anyone calling for him, eg "dinner's ready, are you coming?" will be followed with a "What?! I heard you the first time. Are you deaf?"
Yesterday, when he was stood outside the front door, the doorbell camera caught him saying some vile racist stuff under his breath. This was as a Deliveroo rider was passing on the road.
Helpful? Works hard? Does chores etc?
Not out of his own volition. He would need to be asked and would comply resentfully. Chores like taking the bins out result in slamming doors. Slamming bin lids etc. He will only take the dog out if told to and when he can hunt Pokemons. Generally, he is quite lazy but works on things that he enjoys eg drawing and art.
Is there a clear moment when his behaviour started escalating?
I began noticing the swearing around Easter. He took the Nintendo to school and lost it. Didn't tell anyone until a few weeks later. The Nintendo was his younger brothers Christmas gift. To repair this situation, we agreed that he would work with me in the garden and get paid £10/hr to recoup the money and replace the Nintendo. However, it was April, and I chose to back off as the GCSC mocks were coming up. He has not worked with me in the garden once. He knows that come September, the money will have to be paid. This is a meltdown that is coming I suppose.
How are things at school? Has he settled well, has friends ?
Average student, stable-ish grades—did surprisingly (to him) poorly in a few subjects in the GCSC mocks. His closest friend circle of 5 is trusting and tight. Last weekend he told me about a girl he liked, who didn't like him back. This was heartbreaking to him (and the cause of a separate angry meltdown last weekend) and we talked this through.
What does he say when he’s calm and you talk to him about it? What does he think? What is he feeling?
Admittedly, I often don't want to poke the bear. Bringing up the topics when he is calm can often end with an outburst. On the occasions where its all remained civil and I have asked him to reflect on what happened, he has appeared to be introspective, trying to articulate why things went south. When he tries to explain his feelings, it often ends with "I don't know how to explain it" and I don't push much after that. I prod with a few open ended questions like "If we reset this situation, what would you change first?"
