I find it easier to connect with people online than I do in real life. Go figure.
In real life, I'm rather aloof. I'm sociable when I need to be, but for the most part, I keep to myself. Do I get lonely? Sometimes. There are times that I wish I had friends around with whom I can hang out with. Most of the time, though... I'm fine. Even in college, I was happiest when I didn't have roommates. It's because I learned to live with myself and be happy by myself. I live by myself now and I'm quite happy. Bored because I need a job, but still rather content.
I don't shy away from relationships because they're "all bad" or "everyone's a dick." Granted, past experience plays a part in that, but it's not the main reason. My biggest problem now? I'm a nerd surrounded by non-nerds. A bit hard to connect with people when you have to explain what Star Wars is.
