Most writers will produce better work if they are asked how they think a story should be covered. Writers may propose what the editor could have said, but if writers suggest the approach themselves, the writer will be more committed to it than if they are executing a command. The writer may need a few minutes to think and then respond, perhaps in writing. When writers are listened to, they may surprise themselves by what they say. When the focus or approach changes during the research or writing of a story, I appreciate an editor who will listen and consult on the implications for the final draft.
Silence always means rejection.
The better the writer, the more seriously the writer takes his or her craft, and the more encouragement the writer needs. Talent and concern do not equal confidence, they equal insecurity. And it must be honest. If the writer agrees, then they can move forward to other issues. If not, the misunderstanding needs to be resolved immediately, before going on.
