Funny enough, I think I mask incredibly well. A very extroverted and socially aware friend of mine I've known for over a decade commented that in public I masked excellently and seemed to have an excellent grasp of social dynamics and engaged smoothly with neurotypicals, which always confused him as to the inner workings of my mind. He said that in private, I seemed 'almost autistic', but every autistic person he ever knew didn't 'get' complex social situations, while I appeared to understand them and just openly despise them the moment the target left the room. For this reason I had a lot of asymmetric relationships growing up, where people were attached to me but I was often utterly unattached to them.

Turns out I'm probably Schizoid, lmao.
