In fact, I hate it when they say it in any conversation 
School see it, that as DS is able to do certain things, but then sometimes can't, he's choosing not to.
For example. when doing literacy, he has to write 5 things but he sits there and be everywhere but on task. He needs someone to make it constantly exciting and fun, or a competition when he's like that - then he does it, but even then thats a struggle. Other times, he might be told 'you can stay in then at break' and then he will quickly rush and do it.
I'm getting really frustrated, because I can see what they are saying, but at the same time, in my head - he ISN'T able to because of his ASD?
Am I being unreasonable in my thinking?
