As I've gotten older, I have taught myself to act "normal." I can do it well enough to fool the average person for a whole evening, maybe longer. But it all falls apart if I hear something that elicits a strong emotional reaction from me that is different from what people expect. In an instant, in their eyes, I turn into the sociopathic killer I was believed to be forty years ago.
