I am a man of substance, of flesh and bone, fiber and liquids- and I might even be said to possess a mind. I am invisible, understand, simply because people refuse to see me. Like the bodiless heads you sometimes see in a circus sideshow, it is as though I have been surrounded by mirrors of hard, distorting glass. When they approach me they see only my surroundings, themselves, or figments of their imagination- indeed, everything and anything except me.
