I Am So Proud of You (Don Hertzfeldt, 2008)

“Scattered throughout the box were forgotten photos of himself as a young boy.  He’d read once how each cell in the body replaces itself and dies as the years pass, how everyone is slowly reconstructed out of continuously changing pieces.  It depressed him how foreign the pictures seemed to him now, how his ridiculous ingrown cells had long ago stolen this happy dead kid’s identity and with his own life, made a complete mess of it.”
