We are going to see the behvour clinic at a local hospital to find out if there are any twice exceptional issues. My son at 8 does this as well. They mention that he speaks with little affectation. At home he shows a lot of emotion in his speech. i think he is just bored with them and says things in a flat voice out of aggrevation that he even has to tell them. My round peg does not fit in the square and can really care less what the teachers think. I sometimes wonder if he is doing things purposefully to drive one of them nuts( Its only in her class that the weird noises start). This just freaks her out to no end.
