When I was in high school, the director of an ensemble in which I played gave the orchestra some unrealistic advice. It would have been one thing if he'd told us to count and watch our rhythmic accuracy. Instead, he got carried away and said, "I need you to police each other on this. I need you to say, 'Bill, you are late,' and throw each other off of the stage!"
If we'd taken him up on this, I still wonder if he would have looked on alarmingly or nodded approvingly. Would he have at least offered first aid to the players thrown off the stage?
