So, what I'm writing is a novel where I'm the narrator who describes life events of my another self. The whole story revolves around this character. This page contains the following passage in the First-Person Narration section:
In addition, it also raises the question of how the narrator remembered the events in such detail, down to the exact dialogue, unless they explicitly have photographic memory.
This is called Infalliable Narrator.
My character who accidentally is a writer as well and whose literary work accidentally is written in the same style tries to deal with this issue, but tells that his-my intent is not to convey historicity to the last detail, but only to the main events, while details are only approximations.
But still, will it cause any issues that my narration does not describe all minor events exactly but still involves many of them? Knowing his-my position is essential to understand his-my reasoning of his-my actions, so I can't get rid of them.
