In my lines of work, I sometimes run into people who think they’re real tough.  They’re used to people cowering around ’em and jumping when they take a step.  I don’t like ’em, so I just smile at ’em and talk real softly.  They really don’t know how to react to that.  Their bosses usually like the civilized conversation though.  That makes me money.  Keeps me alive too.  Always a plus in my book.
