I'm at a bustling house party when I notice another guest standing completely still in a corner, not engaging with the crowd. I do what everyone does in a situation like this: I walk up behind them, point a revolver at the back of their head from a distance of roughly one millimeter, and pull the trigger.
What happens next is what often happens in a situation like this: the guest, who has been standing completely motionless for at least 15 seconds, chooses that precise moment to move. I miss the easiest shot in history as my target suddenly jukes to the right and runs out of the room.
