Nah, I used to, but then I realized that I DO have things in common with people. Just because I don't have everything in common doesn't mean I have to isolate myself from them. It just means that some parts of my life are more applicable to certain relationships then others. I'm not a social butterfly by any means and spend a lot of my time semi-alone, but I don't feel alone or isolated. Misunderstood? Sometimes. But I make a conscious effort to BE understood when I feel it's important.
