Also I think posters are right to highlight to you how you are totally minimising your son’s behaviour—the language is so revealing.
“Spending time in the behaviour centre”—he was PUT there for bad behaviour, it’s not the Holiday Inn
“He can be a bit of an idiot”—it sounds like he knows exactly what he can get away it, and how to push your buttons
“And one of the teachers in there touched him” and then he “clammed up”—sorry but this sounds like you’re trying to imply something extremely innapropriate happened? When you’re called out, you backtrack
“I was like WTF” to hearing the teacher touched his arm/patted him, rather than to him misbehaving?
“And he apparently told her she would give him Covid”—talking back to a teacher who was trying to deal sensitively with him
“I guess he just said it to get a reaction out of me”—insightful, then you quickly roll back to why the teacher was in the wrong...
“I admit he is being quite good here at diverting my attention as someone here said...but he is not a bad kid” ... followed by further mudslinging at the teacher and making excuses for him
Why report? “I guess just to share concerns”—NO that is not what you were saying at the start, you’re backtracking because people are calling you out.
“He did not tell her she was giving him Covid in a rude way, I think to be honest he saw it as banter”—he’s in detention and acting like a brat, that’s not banter that’s continuing to defy his teachers
“He also did not tell me ‘in order to make an allegation’”—you literally admitted that earlier! That he only told you to get a reaction from you, as a means to distract from what he did wrong!!!
He’s not a little shit “He was in isolation for refusing to hand his phone over”, “and I think he had a strop over the fucking phone”—this sounds like a fairly big incident to me, and again like it’s being minimised
You just wanted to say “heads up, be careful with Covid”—LOL then you’d mention it to the teacher, not go off in a strip about wanting to make an official report!!
“No one commented on the boundaries I put in place for him, which are quite clealry there”—maybe they are, but they’re defiantly not clear on this thread!!! Honestly I think everyone has been in school with “that kid” who acted like a brat in class, and would then have his mum coming in accusing the teachers of favouritism, unproefssionalsim, etc anything other than just saying her child was acting like a brat.
Back. Up. His. Teachers.
You are undermining their attempts to ensure he acts well in school, it’s not a help to them or to him.
