I just wanted to add that when DS6 was in K last year we had some social issues as well and I have a slightly different thought on what was going on. I don't really think it was "immaturity" as everyone seems to immediately assume. I think, instead, that it was a situation where DS was functioning at a different cognitive level that his classmates yet really really wanted to be in their "group". His reaction was to try to copy what he THOUGHT they were doing. ... He would watch the kids around him roughhousing but when he would try to join in it would just be 'wrong'. When he would try to do what he thought he saw the other kids doing it just came off as awkward.
Exactly - throw in some overexcitabilities, and little justice orientation, and the teachers on some unconscious level wanting a child with a grow up vocabulary to have emotional management skills to match, and yup, there is a perfect storm for 'annoying behavior.'
