I know there is a lot to consider and our brains are on fire with these scenerios. He is not one to do or demonstrate something simply because you ask him, referring to participation and skills. He is content to work quietly alone for long periods of time. He has never enjoyed or joined in despite exposure to birthday parties, storytimes, playgrounds, etc. He likes to make his niche and explore alone or with us. The exception is if adults or older children are accessible he will seek them out. However, this does not seem to be the case with his teacher. I should clarify a patronizing adult he will dismiss.
