Know what I mean?
Movie speech is so “elegant”, every word is perfectly spoken.
But reality is like: “um… so you know… I… uh…”… the spur of the moment, non-rehearsed, reality.
Maybe movies should add more “inelegance” to make them seem more “realistic”.
Sounds a lot like taking the role of Dungeon Master in a D&D game. Your goal is to provide a believable world and NOCs as a backdrop for your players to tell the stories of their characters adventures. For me, it was like having a whole fantasy world running in the back of my mind, and I’d often surprise myself with how that works would react to the heroes.
