I'm a gregarious introvert. When people meet me, they think I must love socializing because I'm a gabber and I also know that if I get people to talk about themselves, they'll just keep talking. But in truth, my favorite company is me. I also like going out alone, especially things that most people don't like going out alone for like bar hopping or out for dinner. I invariably meet interesting people.
Occasionally, I get the feeling that I should like people more because all the "science" says that good social interactions are one key to long life. So I make these efforts to talk more to the neighbors or whatever. This usually results in me locking myself in my home for a few days. Can't help it, people in real life are like energy suckers.
