This is how my plays are written.
I was feeling pretty down today and not at all like writing but I opened the laptop and looked at some of my works in progress. I usually have three or four things working, so I don’t get bored with any one in particular.
I happened to open a one-act play I have been working on, thinking I would just see how far I had gotten the last time. I read the last line I had written and thought of a line in response. Then I thought, well, I better write that one down at least, or I will forget it. So I wrote it down. Then I thought of a response to that line, and I thought, well, I better write that down at least, or I will forget it. Ten pages, later I finally couldn’t think of a response, so I stopped.
This is the kind of in-depth planning characteristic of my work.
