I'm an introvert, for sure! I love spending time alone, and hanging out in small groups... If not small groups, then at least slightly larger groups of people I do know
fairly well. In that case, I am very talkative and don't mind being the "center of attention" for a few minutes. But not for too long, or I get uncomfortable.
If I don't know some of the people in the group, I'm much more reserved and tend to hold back a little more. As a whole, I find being around other people to be utterly exhausting, most of the time. Give me my dog, or one or two close friends, and maybe a movie, and I'm happy!
I think being shy is pretty different from being an introvert. Of course you can be introverted and also be shy, and it's presumably more common than a shy extrovert, but I wouldn't consider them to be a package deal. Shyness, to me, alludes to social awkwardness and a fear of talking to other people (I'm not saying you possess either of these qualities, curlypearl!). Introversion seems to refer to contentedness with solitude, and a more introspective point of view.
