Tuesday Talkback: Best note you ever got

If you've written a script, chances are you've passed it off to a friend or a professional for notes. The odds are equally good that you've gotten back a mix of positive and negative comments. Today I'm asking you to share the best note you've ever gotten.

To be clear, I'm not asking for the strongest praise you've ever received. I'm asking for the most intelligent feedback that someone gave you. How did it help your writing? What did it teach you about writing?
