I often do not understand how people could not see something that seems obvious to me. And I have been told by several people that I am oblivious to how my demeanor is perceived by others and I probably have offended some people without intending or even realizing it.

Also I have no idea why this comment of mine is at -2 karma while this one is at +6. To me they look the same.

And recently I thought that maybe my lack of concern for other people could be because some subconscious part of my brain fails to model them as humans at all. It helps a lot to keep these things in mind, but I have not yet found a pattern of failures that I could easily correct.
