I'm your biggest fan
You are sitting in an empty bar (in a town you've never before visited), drinking Bacardi with a soft-spoken acquaintance you barely know. After an hour, a third individual walks into the tavern and sits by himself, and you ask your acquaintance who the new man is. "Be careful of that guy," you are told. "He is a man with a past." A few minutes later, a fourth person enters the bar; he also sits alone. You ask your acquaintance who this new individual is. "Be careful of that guy, too," he says. "He is a man with no past." Which of these two peope do you trust less?
