Human beings are narrative makers. We remember ourselves and our lives in stories -- stories we tell our friends, family, strangers, ourselves. When a new patient comes to me, I say "tell me about yourself" and await the story of this person's life and how it has brought her to me. And if we work together for some time, that story will change so that the story she tells at the end will be recognizable as hers but different in some ways from the tale told at the beginning.
