2. When with like-minded peers, s/he engages in superficial, loud, and distracting silliness. Alone in public, s/he is self-consciously anxious. One-to-one s/he may display inappropriate or anxious laughter to mask underlying anxiety. With age, becomes increasingly more sullen, hostile, and isolated, with shallow and transparent emotional displays to motivate others.
This is difficult because there was never a "like-minded peer." I've never met anyone like him. Before or after. However, I will speak of similarities and use them as my guide.
When we were engaged with people who had somewhat similar thoughts and ideas he would be a "leader." He would openly and honestly share his thoughts and ideas. He was very proud of himself in this area.
He was never anxious while alone. He was secure in himself not caring what others thought. He would do embarrassing things while in public like impersonate Elvis in song and dance. I think it was more for the shock factor than anything.
As far as later years I can only go on what my son has told me which was that he became more and more depressed and withdrawn as years passed.
