As I headed down to DC for work the other day, my cab driver pointed out something I’d never seen. “See that limo over there?” he said, pointing to a white stretch Towncar emblazoned with a green logo. “It’s from a cancer treatment center. They bring their patients to and from the train station in a limo. Isn’t that nice?” As he spoke, a tall frail woman struggled out of the car, assisted by the driver and an older female companion. She carried the telltale oxygen tank of a lung cancer patient. As she and her companion moved slowly toward the door of the train station, I was instantly thrown back into my mother’s last weeks.
