Sitting on walls, apparently doing nothing, has always been my favourite form of inactivity. But for these walls, and the many idle hours I have spent upon them, I would not have written even a fraction of the hundreds of stories, essays and other diversions that have been banged out on the typewriter over the years. It is not the walls themselves that set me off or give me ideas, but a personal view of the world that I receive from sitting there."
