Bravery

You know you like it when you're players aren't overly paranoid.  They're much more heroic that way.  However they can get too heroic.  Which can lead to them making some less than stellar judgement calls.  Of course if you're playing with the right group this simply becomes hilarious rather than tragic.  It's always a balancing act as a DM.  Lean too far one way on the consequences of the players' actions and they become worried at the slightest inclination of danger.  Lean too far the other way and they charge in headlong at the first inclination of danger.  Both are on the edges of what I prefer as a DM.
