It’s all about perception. Everyone perceives everything a little different from the next person, but there is a huge difference between NT’s and autistics. I would not think that your mom and brother is actually out to get you, but I do believe that their perception of what you say and do, including your expressions and body language does not match your intent. I say this from personal experience – lots of personal experience. The important thing is communication, but communication is all about perception. What is important is that the person you wish to communicate with understands the real meaning of what you are saying. Between autistics and NT’s, that is not an easy task. We are “wired” differently. Misunderstanding is the norm. However, I have learned that I can’t blame them and that they are not out to get me. They just don’t understand me – and I don’t understand them. It is crystal clear to me, but totally misunderstood by them. They may think I am being a bully or a know-it-all, but that is not at all my meaning or intent. They think I am being negative whey I am really being totally positive. It has taken me a very long time to learn this. I still don’t understand it, but at least I am now aware of it. And, being aware of it has made my life and my family’s life much easier.
