I have several concerns about the use of ‘narrative’.
One is that you can/should create a narrative; another focuses on one-way communication through ‘storytelling’.
Narrative is far more than that, and a shared body of narrative forms a substrate for identity, ethics, and, yes, communication, but far more than story-telling, as with common stories, you can tap into a substrate of meaning that goes beyond the words you utter.
