Not sure where this question goes on this forum so I'll just post it here. I was wondering why the cast members tell everyone to step into the "dead" center of the stretching room and to stay away from the walls? Is there any actual point to keeping people away from the walls? I'm guessing it's because one of those door eventually opens but other than that, why do we all gather in the center of the room? I realize this is a pretty stupid question but I'm o.k. with that.
