Here's why:
* Narrative means telling a story. A story needs a sequence of events, a beginning, middle, and end.
* Plot is the driving force of a narrative. It's the arrangement of events, the cause-and-effect relationships, and the conflict that propel the story forward.
While a poem might describe a scene, evoke an emotion, or explore an idea, it's not a narrative without a plot to guide the reader through a series of events.
For example:
* Non-narrative poem: A poem describing the beauty of a sunset. It might evoke emotion, but it doesn't tell a story.
* Narrative poem: A poem about a lost child who finds their way home. It has a plot with a clear beginning, middle, and end.
