The Stage Manager

The stage manager runs the show.

She makes calls to the actors, telling them how much time they have until the show begins.

"30 minutes to places," she'll say. And the actors who hear her say, "Thank you, 30."

It's a good system. The person in charge of saying when the show starts tells the people who are making the show how much time they have. And to signal that they have heard her, they respond so she knows they know. Good, efficient communication. I've been away from it too, too long.

This is the environment I worked in most of my life.
It is not like this anywhere else I've been.
Communication is completely fucked up everywhere else I've been.
And shit gets royally fucked because people have no concept about what is needed for effective communication and lay blame upon everyone else but themselves for the presence of Monumentally Fucked Communication.

But actors are the dumb ones.
