A thing that I just thought about whilst listening to the full cast version of Harry Potter and the Order of the Phoenix: remember the scene in which Hermione confronts Professor Umbridge, stating that she disagrees with the oppinion of the author of the book they're reading? I cannot remember any lesson from my school time where I said something like "but I disagree with what we're reading here, because..." and breaking out into a fruitful discussion. That is sad, I think.
