Have you ever gone back and re-read a book that you remembered loving (or at least liking a lot) only to find that you strongly dislike it the second time? I had that happen recently with a book. I guess my mindset has changed over the years and I found the characters much more self-absorbed and annoying and much less romantic than I did years ago. And then, when the climax of the book came (which I had forgotten), I thought that the revelation was annoying and stupid.
I wonder if it would happen the other way too ... maybe something I really didn't like before, I would enjoy reading now. The problem is, of course, that I disliked it so why would I pick it up again.
