Something wonderful happens to you and you instantly look back over your life and see it as a series of fortunate events stretching off into the distance like mountain peaks. Something terrible happens and your life has always been a litany of woe. The present rearranges the past. We never tell the story whole because a life isn't a story; it's a whole Milky Way of events and we are forever picking out constellations from it to fit who and where we are.
