Hacks use repeated, and specific, actions with their characters. Editors search the manuscript for these actions. If found too often, they reject the work so they can move to the next project. Those actions are:
1. Characters who always roll their eyes.
2. Characters who always sigh.
3. Characters who always smile.
4. Characters who always laugh.
5. Characters who always cry.
6. Characters who always whine or complain.
7. Characters who always curse.
8. Characters who always get drunk.
9. Characters who always win.
10. Characters who always avoid conflict.
See if any apply to your characters and correct.
On a side note, what behaviors do you see an author repeat to point of irritation? I know a famous author whose female protagonists always tuck a loose strain of hair behind their ears. And I mean once or more in all his books.
I wonder if it's code to his wife or something. . . .
