Books are a contentious subject. I love books for themselves, even if they're dog-eared old paperbacks. A space-clearer would chuck them. Some people can do that - such as my nanny, Amanda, whose flat is beautifully clear. If she buys a new ornament, she dumps an old one. "I don't keep things I don't need," she says. "Why keep a book I'm not going to read again?" I can, and so can my friend Antonia: "It's a chunk of your mind you're throwing away," she says. "I still like looking at my A-level Tennyson text-books, with all the underlinings." Dawna might allow books to stay, because at least they can be marshalled onto shelves. Photographs should be put in albums, framed on walls, or ditched.
