I think I know what you mean. Sometimes when I'm out in the world, it occurs to me just how far I am from anyone who knows or cares about me. And it's liberating to know that no one cares. That the world doesn't exist for me to explore. It just exists.
I think we know why Little Miss Sandybum has enough followers to colonise Mars. But sometimes I wonder if I'm all that different. She shows off her butt, and I show off my words. It's just my bad luck that people like butts more than they like words.
