A fellow writer-in-training expressed concern to me because she had written a line of narrative which shocked her.
I don’t know where it came from, and it makes me really uncomfortable. I know I should probably cut it, but a part of me really wants to leave it in.
Never cut it. Ever. Writers should make themselves squirm, sweat, and shift uncomfortably in their chairs by what they write, because those shocking paragraphs are the ones that make a book memorable.
