I am a self-proclaimed introvert. I tend to think about small "mistakes" I made socially and how I could have done better. However, I enjoy being around people, just a small group of people all of whom I know. I like to be engaged in a conversation, and if put in a situation with a large number of people (such as a party or "social gathering") i will spend most if not all of the time with the same people. It's not that I don't like people, it's just that to connect with them I have to have a conversation with them of greater length than happens at such social gatherings - and it just so happens that the people who enjoy these conversations are other introverts, creating the appearance of the introverts hanging out at the edge of the crowd and talking with other introverts.
