I got back the changes to the Gear School script from Dave the other day. And besides the usual typographical changes one expects, he also asked me to take a look at a scene. Now, I was expecting him to want me to ramp up the action sequence or something, but, no, he wanted me to look again at a quiet scene that just features two characters talking. He thought that the point I was trying to make was confused and maybe too subtle. I re-read the script again tonight and, what do you know, he's right.
I'm reminded of something William Stafford once said at a reading I attended. He said, "An editor is your friend who only wants your work to be the best it can be." That's held true in my experience so far.
