Oh dear. I don't know if you're ready for this can of worms you just opened...
I say I'm an extroverted introvert, but really I think I'm just in the middle, like
@Pea-n-Me said. I don't like crowds, but a lot of that is because of my size. When I'm in a crowd, especially when getting out of a crowded area, I immediately feel lost because I can't see well around me and I walk slowly, so I feel like I'm about to get trampled. That's a slight exageration, but let's just say I HATED passing period at high school, and it took me until a few years ago to really figure out why and realize it was so much more than being nervous about getting to class on time. It was more like a race to class to get out of the hallway. I also like my alone time, but couldn't be in a large house alone. Tried that once when I was cat/house sitting and I hated it. I also don't like too many social events at once. And at social events, I tend to keep to myself, but if others seek me out, I'll chat up a storm. I don't like initiating social interactions, but really don't mind being part of them. But I can talk to anyone, and I don't mind small talk. (my job revolves around talking to strangers, actually, and not in a call center way, either) Oddly enough, in a lot of situations I'm MORE comfortable around strangers because.... I guess they won't see me again? Like... I"m more comfortable singing/performing in front of a crowd of strangers than I am singing/performing in front of a few people I know well. An audition is worse than the performance! Ha! I don't even know how to describe myself on the introvert/extrovert scale, but most "quizzes" I take I fall on the introvert end, mostly because I don't like large events?? I'm... just a weird combination.
