Answer:
Sometimes the narrator has an opinion on things and takes sides. But if most people agree on a choice, the narrator usually agrees too. For example, in a fairy tale, snow white fell asleep and most people wanted snow to wake up. (The dwarves) But only the evil queen and her servants wanted her to die. SO if the narrator said
