A stage play is basically a form of uber-schizophrenia. You split yourself into two minds - one being the protagonist and the other being the antagonist. The playwright also splits himself into two other minds: the mind of the writer and the mind of the audience.

Here's what happens in a play. You get involved in a situation where something is unbalanced. If nothing's unbalanced, there's no reason to have a play.
