I say that because I have a reputation, carefully honed among those who are aquainted with me (but not close to me) of being anti-social, hard to get along with, capricious, etc. I do that, however, because I'm a "node of knowledge" type, and anyone and everyone wants to come up and pick my brain. I can't spread myself so thin that I can't do my job VERY well, so I put up a facade that causes people to ask themselves if they truly NEED to come to me with their problem. Those who do get the "Gruff" until I determine whether or not they truly need me. If they do, then I allow a bit more of my REAL personality to express itself (helpful, eager to please and to see appreciation for my effort, joking, playful). IF they don't abuse the "peek" at the real me, they end up in my inner circle and I'm always helpful and friendly. If they DO abuse it, they go back in the "I need to be seen as a sociopath by that person" group. The oddest thing is to see the change in the occasional person who gets into my "inner circle"; frequently, they realize what I'm doing, and why, and end up adopting the same type of behavior in order to help them focus down and do a better job, too.

Or that could be the definition of Anti-social culture change.
