DS1 is gorgeous. he is gentle, really loyal and kind-hearted but he talks at people for ages and has no idea how to have a conversation. My DF, DH and DS's brother are all ASD and although DS hasn't been diagnosed people have occasionally assumed he was also ASD because of this habit of collaring people and talking at them about his passions.
In conversation he will politely wait his turn but then say what he'd wanted to say before the other person started talking, instead of replying or saying something that develops the discussion. DH does this too. I really want to teach him how normal conversation works before he gets a reputation at school for boring people. He is passionate about music and politics and knows lots of really deep detail about both subjects that no one else cares about but he shares it anyway. He can come over as dominant because of this, he's always first to reply and assumes leadership roles whether or not he's suitable for them. But he's supersensitive underneath. When I commented once that he needed to take second turn more often and let his brother take the lead occasionally, he went scarlet and silent and didn't go first in anything for months afterwards.
I don't want to crush him by being too direct about it, but he really is getting too old to get away with talking at instead of to his teachers and his mates. WWYD?
