My high school best friend is in town to sit by the bedside of her mother and wait for the inevitable. One day, one moment, very very soon, seventy years of love and laughter and life is just going to wink out, like a light being turned off. When I think about it, I cry, but I can go hours at a time without thinking about it. I wish my friend could escape from it from time to time like I do, but nothing sits furthermost in your mind than the sure and immediate knowledge that your mother is dying....
