Around other extroverts I feel like an introvert, and around introverts I feel like an extrovert. When first meeting me, people usually tell me they thought I was either intimidating, shy, or seemed "pretentious." The thing is, I usually observe people before I start busting out the humor, so I can gauge what sort of things I can get away with. Sometimes though, I just don't care, and I let it out anyway. Once I start opening up, I can usually charm the pants off anyone in the room.
I have a million acquaintances. I think I know a lot of people but a lot of those people don't know me. I like to keep people around for networking. (Yeah...I'm one of those "user" people...) I only have a very, very select few friends that I feel actually know me, and I feel legitimately close to. And those are the people I prefer to hang around the most, especially because I "gain" a lot of energy being around them.
It seems like the feeler extroverts can't really stand (or particularly like) being alone for long periods of time. It doesn't bother me at all, however, I DO like to be around people I enjoy, and do not have to tolerate. Bouncing off crazy ideas to my other N friends is too much fun for me
