A sentence that would fit into a piece of literary nonfiction but not expository nonfiction might be:
"As the sun dipped below the horizon, casting a golden hue over the quiet town, I couldn't shake the feeling that something profound was stirring beneath the surface of everyday life."
This sentence evokes emotion and paints a vivid picture, characteristic of literary nonfiction, while lacking the straightforward, objective clarity typical of expository nonfiction.
