Today, I saw the blind leading the blind.

They were an elderly Chinese couple -- he was tall, and sported a long, scraggly beard in the manner of wise men; she wore her hair bound back in a colourfully embroidered wrap, like the women of her homeland. They both grasped canes, but he led; as the subway doors slid open, with her mittened hand laid on his shoulder and her forehead bent down towards his back, he brought her across the threshold like a groom guides his young bride, shaking bells to announce their way.
