I think this quote sums it up best: "All rooms were dark until light came. And here she was, in all of them at once. And she was not alone. Her grief was but one part of a vast grief, her fear only one of countless others. And this grief was only a half thing. There was the other half; of things born, of comfort in the shape of a new child, of food in the warmed body, of colors for the eye and sounds in the awakened ear, and spring wild flowers for the smelling." - Ray Bradbury Haunted Ghost
