What is a “leaving without goodbye”? Dr. Pauline Boss labeled one type of ambiguous loss as “Leaving without Goodbye”. A typical example is when a family member goes missing during a disaster. It refers to a state of physical absence, but having a remaining psychological presence, because there is no certainty of death. This type of loss is not limited to the aforementioned missing due to disaster or distress, but also includes disappearances, kidnapping, loss of home or hometown, divorce, etc.
