Yes it made me so sad when he was questioning his role in his friendships and if he was the guy they tolerated rather than enjoyed. That really hit me. Something we all wonder and deal with but I know for him it felt so much more. He was so smart and so aware of what made him "different" etc. I can't imagine what his brain was like, he probably could not turn it off. While I can't understand his actions I respect them and I hope he is at peace now. RIP Kegan.
That may be the one thing all higher functioning autistics or 'neuro- different' people have in common. They are aware of it. My oldest son is in that same position. Otherwise, I think the old saying applies:"If you've met one person with autism, you've met one person with autism."
