A note from my friend reprinted without his permission:

Playwrighting
I notice that a lot of my perception of life and the way I write is heavily influenced by theatre. I see someone on the street and think,"Oh, I want to write a character about him", or I'll be driving down the street and see an interesting building and I'll think about how I would interpret that into a set design. Even when I write my own thoughts down in my own, personal journal, it's spewed out like a monologue; or I can hear the way I would say it aloud to an audience in my head.

Ha. Mary Karen said the other day "every text implies a performance." For me that means that the written word always implies the spoken word. Every word that has been written, formed first in the mouth. It was spoken before it was written. If each word contains its own history, then each word that we read also contains the word as it was spoken. A tangent? What Mary Karen meant, too, I think, is that for theatre people, we always see a text as performative (performable?) because we, as artists (as people) are concerned with performance and the power of performance.
Further,
Blogging and journal writing are performance. You write for others to read. You write for an audience. It is the very essence of performativity.
Is blogging theatre? A question for another day.
