I pretty much hate all of these questions, so I'm lumping them together in what will be a short and not very interesting post.
Day 17: Favorite quote from your favorite book:
I don't have a favorite book. I have favorite books. If I post a quote from all of them, this post would never end.
I'll just mention two, specifically, that I really like:
"Promise me you'll always remember: you're braver than you believe, and stronger than you seem, and smarter than you think." A.A. Milne, Winnie-the-Pooh
"The one thing that doesn't abide by majority rule is a person's conscience." Harper Lee, To Kill A Mockingbird.
Day 18: A book that disappointed you.
I just can't even answer this. There are so many different levels of disappointment: books that didn't live up to my expectations, but which were still good; books that have been overhyped; books that actually suck; books that I can't figure out how they ever got selected for publications; books that were written by celebrities that expose the narcissism that is rampant in our culture; books by people that I admired until they wrote a book.
I reject this question.
Day 19: Favorite book turned into a movie:
Pride and Prejudice by Austen. I like both the BBC production with Colin Firth AND the newer version with Kiera Knightly. Although each of them has it's own problematic scenes: in the BBC version, Colin Firth swimming in his regency smallclothes is swoonworthy, but ridiculous; and the last scene in the Kiera Knightley version with Lizzie and Darcy in their jammies on the patio at Pemberley just makes me cringe.
