Appreciate the note at the end, though, I wanted to make something clear.
I have a bit of an issue with calling the facts and statistics of her height as it relates to the real world "objectively tall." It's not that this phrasing is untrue, but it makes it seem like the elements of the story that actually matter aren't objective. How she and her peers see her and how it relates to the story in the world is 100% an objective aspect of the story. The facts of our world are no more objective than the elements presented within the story, as well as how that story is executed. The reason why I bring this up is because I think this sort of confusion around terminology is how we get into arguments about if we can be objective about media. The contents of a story and how that story is told is just as objective as the facts of our world.
Other than that, nice explanation. It's always good to keep these sorts of things in mind. Cultural context can often be a large part of a narrative.
