My Character

Okay, this is a more serious entry. I'd like to talk about me and maybe get some feedback from my (so far, only) user as well as get my words out on paper... or type.
I'd like to talk about me in relationship to others. I have recently been asked, "are you a people person?" and I don't quite know how to answer. Sure, I LIKE people, but whether or not I always enjoy their presence is another story. There are exceptions, but more often than not, I'd rather be spending what limited spare time I have doing things I enjoy doing. For me, this is reading a book, playing the piano, watching a movie, creating something or gaining knowledge. It's hard to do those things with other people because who wants to get together with a friend to READ A BOOK, and if I played the piano with some of my friends, they'd accuse me of showing off. Face it. Some things are better done alone, and I happen to really enjoy those things! Does this mean I'm not a "people person"?
At the same time, there are some things better done with groups. I can't TALK to nobody. Sure, I write things down a lot, and that's sort of like talking, but It's hard to get a response out of paper or type. When I have a question, I often ask one of my friends or my sister and they give me great advice. I can't party without friends. Most of the time, walks to the park or going out for ice cream are better done with friends.I'd hate school if my friends weren't there. And friends, as Thaddeus told me once, are things a person needs -- things a person must hold on to. Friends are helpers and supporters. And yes, sometimes my normal alone activities get boring and I want to see other people. And when I'm with them, I usually have a great time! I'm sociable. I like talking. I like hearing from others -- learning about others. If you know me at all, there are times I can't keep my mouth shut. And there are times I like to goof off, and have others goof off with me.
So what does that make me? And introvert with extrovert tendencies or an extrovert with introvert ones? Or does that make me neither? Thaddeus told me I was an introvert (but he doesn't know as much about me as he thinks he does.) Mom tells me I'm an extrovert. (But she doesn't see me at school or with my friends that often.) If any of you wish to comment, please answer that question if you can, based on what you know and see about me. What am I?
Can you stereotype a person that way at all? I mean, we all have habits, but I think people like to be balanced in their lives. Part of this balance is deterimining how and with whom you spend your spare time. We all are looking for ways to achieve this balance, aren't we?
You're probably wondering what brought this on. Well, these past few days I've been taking part in some studies on neurological development in adolescents at the University of Minnesota (that means some college kids have been checking mine and other teens' heads to see how we behave). They've asked me a lot of these types of questions and I often had trouble answering them because I don't KNOW what I want! That's part of a lot of what I try to write here. I'm trying to find myself and find a way to TOTALLY define life to the fullest ability.
