my high school english teacher would often critique our literature analysis work by pointing out: "you're treating these characters like they're real people. They're not. They're characters". And it took me a long time to understand what he meant by that. Because I always thought "isn't that the point? That writers want to write characters to be so three dimensional that they act and feel like real people?" but that's not it.

Characters are tools a writer uses in service of a story. Of course characters can be written with depth to the point they feel real to us, but they exist in service of their narrative. Something real people aren't beholden to at all. When discussing characters, I think it's easy to accidentally see these characters as "real people" and not extensions of the author's beliefs. Tools for a narrative. Means of storytelling.
