Meh. I'm a classic extravert, and yet I found myself nodding to some of them:

1) Withdraw from crowds
2) Bored by small-talk
3) Locate near exits
4) Can't stand the phone

My reasons have nothing to do with factors on the extra/introversion continuum, though. One and three are related to the fact that, while I derive great energy from interpersonal interactions, I'm not particularly trusting. Two is related to intellectual demand... move the small-talk to something interesting and/or amusing to me, and I'm all in. Four is because it hurts my ear, but if I can set it down and put you on speaker, I'm good.
