““Loss is a straightforward equation: 2 - 1 = 1. A person is there, then she is not. But a loss is beyond numbers, as well as sadness, and depression, and guilt, and ecstasy, and hope, and nostalgia - all those emotions that experts tell us come along with death. Minus one person equals all of these, in unpredictable combinations. It is a sunny day that feels completely gray, and laughter in the midst of sadness. It is utter confusion. It makes no sense.””
