"It is easy to see the beginnings of things, and harder to see the ends." So Joan Didion begins her famous essay "Goodbye to All That," about arriving in--and eventually leaving--New York City. Write about a time when you left something--a city, a country, a job, or a lover. Include details about how things began, but focus most of your attentions on how they ended. For inspiration, read or revisit Didion's essay, originally published in her essential collection Slouching Towards Bethlehem (Farrar, Straus and Giroux, 1968).
