A story is told as much by silence as by speech.
If there is a doctrine, a message behind Live, it's just that wordless intensity that doesn't necessarily have to mean anything.

You can express a lot of things, a lot of action without speaking.
I've seen plays that are, objectively, total messes that move me in ways that their tidier brethren do not. That's the romantic mystery of great theater. Translating this ineffability into printable prose is a challenge that can never be fully met.
To choose to be silent in any scene sometimes has more notes in my script than when you chose to speak.
