I genuinely think that the vast majority of English teachers have had experiences like this. It's what made them become English teachers.

Then, with all the best intent in the world, they try to explain to their students "Look, you don't get this, this fat book is transcendent if you can just sit with it and understand it! I, too, used to think that English class was just stupid words that they force you to read, but let me help you get this! You've got to..."

But all their students hear is Charlie Brown's adults going "Waa waa waa..." because they're genuinely not mature and experienced enough to "get" the book the way the English teacher understood it.

Ten years later a student will re-read one of their literature books, have this same epiphany, and talk excitedly about deep literature is, and someone will tell them they ought to be an English teacher. And the cycle continues.

Ok, so some English teachers are of course better than others, and some will convey their excitement a little better, and some students will be mature enough to understand it better than others.

But I will definitely maintain that all (close to all) English teachers have this same love of books, and want desperately to pass it on.
