As for my father, few souls are less troubled. He can be simply pleased with us, pleased that we exist, and, from the vantage point of his wondrously serene old age, he contemplates our lives almost as if they were books he can dip into whenever he wants. His back pages, perhaps.
I believe that appreciation is a holy thing--that when we look for what's best in a person we happen to be with at the moment, we're doing what God does all the time. So in loving and appreciating our neighbor, we're participating in something sacred.
