Wait, do they not understand her because she plays silly and acts dumb, or for the opposite reason (she gets everything right and feels isolated)?

DS6 has dumbed down his work at times to "match" his friends. He is asked for help a lot in the classroom and decided to start asking other people for help, too. He then got wrong answers but wrote them down anyway to be polite. At least, this is what he tells me, and I think it's probably true. He's a little weary of sticking out.
