There are no obstructions here, no inside or outside, no room or lack of room, no hiding place or shelter: I can find no home here to live in or to be locked out of, and not an inch of ground to build it on. But this homelessness suits me perfectly - a void needs no housing. In short, this physical order of things, so solid-looking in appearance and at a distance, is always soluble without residue on really close inspection.
