I am an invisible man.
No, I am not a spook like those who haunted Edgar Allen Poe;
nor am I one of your Hollywood-movie ectoplasms.
I am a man of substance, 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 see sometimes in circus sideshows, 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.
