Whenever they love a book, they can't help but force everyone else to read it too — and they love a lot of books. They basically consider their bookshelves a library, and they are constantly trying to keep track of all the books they've lent out. "Have you read such and such? No? You have to! Kelly has my copy, and Erin's next in line for it, but after that, I'm giving it to you because it's everything. Promise."
