Every one of them could be someone else, and could be represented by some third party who is identical with a fourth, without anyone noticing it. A man says. The woman says. A horse comes to a dentist and tells a joke. No, I don't want to get to know you.
Actors tend to be false, while their audiences are genuine.
For we, the audiences, are necessary, while actors are not. For this reason the people on stage can be vague, with blurred outlines. Accessories of life without which we would leave again, pocketbooks glued to the slackening crooks of our arms. For every move on stage a certain quantity of liberty is available from which the actor can take a portion. There's no secret about that.
