Well, the Ursula K Le Guin Carrier Bag Theory of Fiction is really interesting. It's a theory that rethinks how we construct and understand stories. In many traditional stories, there's a focus on a central, often male, hero who goes on a big, important quest. But Le Guin's theory is different. It's like saying that fiction can be more like a carrier bag. You can put all sorts of stuff in it. It could be the simple conversations between neighbors, the way a community functions, or the little rituals of a culture. It broadens the scope of what can be considered important in a story and how we can tell stories that are more inclusive and representative of the real, messy world.
