To you I say (or, rather, Joe Queenan says):
People who need to possess the physical copy of a book, not merely an electronic version, believe that the objects themselves are sacred. Some people may find this attitude baffling, arguing that books are merely objects that take up space. This is true, but so are Prague and your kids and the Sistine Chapel. Think it through, bozos.Yeah!
