As an autistic person, I kind of get self-conscious when people point out that I know a lot about a subject. Even when they mean it as a compliment it still kind of bothers me and I'm not sure why. For me, the amount I know about most topics doesn't feel impressive to me at all. People around me think I have encyclopediac knowledge of movies when I actually know very little about it compared to how much there is to know, I just know more about it than most of the people around me and am better at remembering facts than most people around me
