Here's why:
* It's a structural element: A frame story is a narrative technique where a story is told within another story. It provides a framework for the main narrative.
* It serves a purpose: Frame stories can be used for various purposes, including:
* Setting the scene: The outer story can establish the context, time period, or atmosphere for the inner story.
* Adding layers of meaning: The frame can provide commentary on the inner story or offer a different perspective on the events.
* Creating suspense: The frame can raise questions about the inner story or hint at its importance.
* Enhancing realism: The frame can make the inner story feel more grounded and believable.
Examples of Frame Stories:
* "The Canterbury Tales" by Geoffrey Chaucer: The stories told by the pilgrims on their journey to Canterbury form the frame story.
* "The Arabian Nights" The story of Scheherazade telling tales to save her life provides the frame for the many stories within the collection.
* "The Princess Bride" The story is told by a grandfather to his sick grandson.
The frame story is a versatile and effective literary device that adds depth and complexity to narratives.
