Pauline Boss is professor emeritus at the University of Minnesota. She is the author of, among other books, "Loving Someone Who Has Dementia." Boss offers the perspective that the idea of closure leads us astray, "a myth we need to put aside, like the idea we've accepted that grief has five linear stages and we come out the other side done with it. She coined the term "ambiguous loss," creating a new field in family therapy and psychology. She has wisdom for the complicated griefs and losses in all of our lives and for how we best approach the losses of others." This in-depth interview shares more.
