I probably am being unreasonable and am prepared to hear it.
My DD1 has just started secondary school, she is in the "more able class" (this is what its called by the school 
).
In this class, of about 20 odd, there is a boy with SN. He has an assistant for every lesson, and from what my DD tells me I guess he must have some form of autism.
But every single day, she is coming home with stories of what "X" has done. Thinks like having tantrum, which takes 20mins to calm down disrupting the lesson, shouting at the teacher, grabbing or hitting another child (and once a teacher), throwing all his books and stuff on the floor (numerous occasions), storming out of lessons etc etc.
Now the kids all seem to think this is hysterical (and great fun that almost every lesson is disrupted by "X"), but every day I am a bit , it just sounds very disruptive, and DD is starting to sound more annoyed than thinking its funny.
She does however say that is is clearly very bright indeed.
I know he has just as much right to be taught, but at the cost of disrupting a whole class of children? AIBU?? I can't quite decide TBH, and so far it doesnt appear to be affecting DD1's abilities, but we are only a term in.
