I have long said that I have a special tattoo across my forehead, visible only to crazy people, lunatics, schizophrenics, and the like. It says, "Hey...I'm your buddy."
Take, for example, this fellow. He marched right past 25 other people seated in an outdoor ceremony commemorating the 60th anniversary of Grandma and Papa Biscuit, smack in the middle of the service, stopped right in front of me, and asked that I take his picture. With my camera. Now we're buddies.
