A lifetime manufacturing small myths
You discover that your memory has spent a lifetime manufacturing small myths to keep your life story consistent with who you thought you were. You have committed to a coherent narrative, misremembering little details and decisions and sequences of events. On the way back, the cloth of that story line unravels. Reversing through the corridors of your life, you are battered and bruised in the collisions between reminiscence and reality.
