OK I'm a bit crueler lately because with my new knowledge, I realized many times in the past, that dude made fun of me. All the while I thought they were just boring but overall positive experiences.
It never makes sense to me why anyone would do that because “Don't you want to spend time with people you can be real? Why waste your own time being miserable?”
But people like him function on a different dimension of the universe. And with the great power of rationalization and the need to be socially admirable, one can convince oneself to do anything.
When we were kids, I took his bluntness as a sign of authenticity. But it wasn't. It was a sign of lacking understanding of social dynamics. I chose to be blunt after knowing the cost of it. He was blunt because bluntness was natural and didn't cause him trouble at that point, as autistic boys often face social consequences later than girls. Once they understand the social game, most autistic boys choose the reward of being players.
