Generally, there are two categories of misperception, and they do overlap, to some extent.
1.) I am, apparently, perceived as; Arrogant, aloof, egotistic.
2.) I am, apparently, perceived as; Selfish, lazy, paranoid, negative.
The first category is usually the mistake of people that I meet that, frankly, don't measure up to my standard of association. They're usually (but not always) nice enough people, good folks. It's just that it only takes a few seconds of conversation to discern that I have zero in common with them and there's therefore no point in wasting any more of my time or THEIRS (see? NOT selfish) in further interaction. They want to talk about sports, cars, and their latest exaggerated exploits by way of self-promotion (Lies), and I want to discuss human origins, cosmology, art & music. Not much point in continuing in that direction, is there?
The second category is primarily my father, who, because he cannot see the world through my eyes, and has not experienced what I have, dismisses any conclusions at which I arrive that differ from his own. If I dismiss the suggestions he makes, I'm being negative or paranoid. He often takes these dismissals personally, and his accusations are, IMO, a form of striking back at me. He undermines me at every turn, then expects me to rise above it at the very same time. Faced with this dilemma, I shut down. Often. He is my only living relative.
