I don't hate people. I just don't connect on a deep level with most (as is the case with almost everybody). If I don't feel and experience that deep connection, then it's not interesting to me...I enjoy deep relationships rather than surface acquaintances, which is another component of introversion. Extroverts, on the other hand, just love being around people and are fine with any sort of relationship, deep or shallow, they just thrive when people surround them.
I suspect most of us here are introverts. I'm guessing that extroverts would not go to a forum for advice. I think they'd throw it out to their friends/acquaintances.
I have some extroverted traits...very friendly with people I don't know well, like the cashier checking out my groceries. I am very talkative and can joke around with the crowd at work, but usually I'd rather listen to the humor and laugh and enjoy it from my spot.
Conduct Disorders, the site, has had meet ups and I've never gone, even when it was in Chicago. Part of that is I couldn't go with ease at the time due to something else that I can't recall. But I would have been terrified if I had forced myself to go. I don't do crowds well. That's when I either get very quiet or screw up and blurt out something stupid that sounds weird and everyone kind of looks at each other (it's nerves). I would do much better in crowds if I drank...lol. But I don't and won't (I take medication and drinking is also NOT my friend) so I have nothing to buffer the anxiety accompanying meeting people that matter to me, but whom I don't really know. The more I care, the more I seem to become tongue-tied. I'd rather write.
