A smile. A hand shake. Or just a look. Sometimes, this is all it takes.
There is this cool guy that comes around once in a while. He has talked to me once in a while, and it's a really cool guy. A little nerdy, somewhat cool, maybe a geek, I don't know, but he always comes, says hello, smiles at me, and walks away. I respect people who do that. I love when people I don't know come to me and start a conversation. You don't see that so often these days.
Sometimes, when people approach me, I tend to give them some unusual backstory. I don't know if it's because I read too many comic books, or if that's what every writer does, but I entertain myself in figuring out the person with what little he or she says.
