All drama is about lies. All drama is about something that’s hidden. A drama starts because a situation becomes imbalanced by a lie. The lie may be something we tell each other or something we think about ourselves, but the lie imbalances a situation. If you’re cheating on your wife the repression of that puts things out of balance; or if you’re someone you think you’re not, and you think you should be further ahead in your job, that neurotic vision takes over your life and you’re plagued by it until you’re cleansed. At the end of a play the lie is revealed. The better the play the more surprising and inevitable the lie is. Aristotle told us this
...My dad, may he rest in peace, taught me many wonderful things. And one of the things he taught me was never ask a guy what you do for a living. He said "If you think about it, when you ask a guy, what do you do you do for a living," you’re saying "how may I gauge the rest of your utterances." are you smarter than I am? Are you richer than I am, poorer than I am?" So you ask a guy what do you do for a living, it’s the same thing as asking a guy, let me know what your politics are before I listen to you so I know whether or not you’re part of my herd, in which case I can nod knowingly, or part of the other herd, in which case I can wish you dead.
