Curiously though, in this allegory of the stage, it isn’t other people who are spectators of your life. Everybody is either on the stage or waiting backstage for their moment. What’s out there is the universe itself, random, indifferent to your strutting. That’s what separates teenagers from adults: the realization that other people are not your audience.
