a man walks into a bar
you are sitting in an empty bar in a town you've never before visited, drinking baccardi 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 aquaintance who this new individual is. 'be careful of that guy, too,' he says. 'he is a man with no past.'
which of these two people do you trust less?
