> I hated the question of teachers asking: What does the author wanted to tell us with this story." Because -> The author never wrote that down. And deriving their intentions from a fictional text felt just like making shit up.

Then why does anyone write anything? Why did Orwell write 1984 instead of just making a 2 page bulleted list about how authoritarian regimes are bad?

Sure, an author can write something that is interpreted totally differently from what they meant, but that doesn't detract from the fact that they did have some intention behind what they wrote and it's worth exploring that.
