Have you ever reread a book and found that your opinion changed?
Yes. In high school I was assigned Light in August by Faulkner, and the first time I read it, I violently disliked it. Something about it just annoyed me. But when I reread it to prepare for one of the assigned essays, I found that I actually enjoyed it. It's still not my favorite book, but I managed to appreciate the writing and the story.
