the world is shrinking everyone is getting smaller

Is alone-ness a bad thing or has it only been portrayed so by popular culture? I know for myself being alone is a large part of my character. The more I'm around people the harder it becomes for me, so hard in fact that I tend to actively avoid it. And I have many friends who are exactly the opposite, who crave the social atmosphere to the point that this craving is a large part of their personality. Some days though I have visions, maybe more like fantasies, of myself surrounded by other people, and I'm confounded with conversation; everyone is talking very rapidly and I'm right in there with them, mixin it up.
