It's good to be able to explain it afterward.

I used to spend time with my wife's uncle who is probably on the spectrum and he would have massive meltdowns any time something unexpected happened. He would usually blame other people, even after the fact. He's a very bad person though and he bullies other autistic people over his own insecurities, which he denies. He would constantly imitate an autistic kid he saw at the mall and when the three of us went to see Ready Player One, he started laughing to himself and mocking the programmer character during the movie.

My sister was diagnosed and I'm aware that he doesn't represent the overwhelming majority of autistic people. He used to bully her as well and was absolutely obsessed with the fact that she was a virgin before transitioning.
