Here's why:
* Parable: A parable is a short story that uses symbolism and allegory to illustrate a moral or spiritual lesson. The characters and situations are often not intended to be taken literally.
* Fiction: Fiction refers to any imaginative work that is not based on fact. Since the two brothers are not based on real people, the story is a fictional creation.
