Wandering around backstage, you suddenly hear a roar of laughter from the
audience to the east.  A giant spotlight illuminates your face, temporarily
blinding you.  You are struck by a sudden realization that you've stumbled
onstage in the middle of a performance.  
An actor is busy performing a play.
