Can I be both?
The thing is, it all depends on who I'm with.
I am terribly shy around people I do not know,
especially adults. Oh, my goodness. I can't stand talking with an adult I don't know. I hate, hate, hate when I have to purchase something and speak with the salesclerk. And I don't like having big groups of people, unless I know everyone in the group personally. When I'm by myself, I feel so very lost and I can't talk to anyone. I hate going to big events. And I generally prefer to spend time alone – I rarely get together with my friends outside of the school day, preferring video games, writing, or other solitary activities.
However, as soon as I get to know someone, I exhibit EXTREMELY extrovert qualities. It's funny – suddenly, when I'm surrounded by friends, I'm no longer shy, and I'm much more willing to meet new people. I talk very loudly when I become excited, and my sister gets very embarrassed and scathingly points it out, but if I'm with friends, I don't care. I really don't. I'll giggle and laugh loudly and scream and go on rants about Zelda, and I don't care what others think.
After reading the Wikipedia entry, I'm even more confused. I like most of those introvert activities: I'm an avid writer and reader, and I prefer close friends than meeting new people. I really hate parties and only go if it's with a good friend. But I'm not so sure – I'm terribly outgoing when in a group of people I know well. Maybe I'm that third one – ambiversion?
Ah, whatever. I have no idea.
