Dots, I love Stephen King's On Writing, too. In fact I got one of the dialogue editing tricks I mention in The Frugal Editor from him (and credit him, of course!). That is: When you are writing dialogue and the character is asking a question you don't need BOTH the question mark at the end of the sentence AND "he asked" as a tagline.

See what I mean about so many little things marking you as a professional...or not? How can we know everything when we start? How can we ever even consider not continuing that learning process? I try to read at least one book on writing a month. Sometimes I learn little. But I always learn something! (-:
Love that editor of yours, too. She was like my first newspaper editor. I thought she was an ogre but, boy, did I learn from her! (-:

Love,
C.
