The Chambered Nautilus

He moves by necessity from one room to the next. The passage way closes behind him; there will be no going back. Past is past. Gone. Irretrievable. And he will stay in this room only briefly, before moving to the next, and the next after that. Each one larger. And so it goes. Then one day he shall exit through the final passage, leaving this house forever, never to return. It will have become to small to meet his growing needs. All that remains are the former chapters of his life. He wonders where the next ones shall be written.
