The bird from the Mad Hatter’s unanswerable riddle:
…‘Why is a raven like a writing desk?’”
(My favorite answer is George Simmer's: "Because one is good for writing books and the other better for biting rooks.")
I learned gazillions of things doing it, even though it was not my first pony ride. Like, for instance, when hardcover collectors say they want "special features," they mean they really do want art, story and added features not available in other editions. It sounds obvious, but there are rules to it, and I've come to respect them. I ♥ lovers of books, especially because they seem like a slightly endangered species.
