"They say that dogs may dream, and when Topsy was old, his feet would move in his sleep. With his eyes closed he would often make a noise that sounded quite human, as if greeting someone in his dreams. At first it seemed that he believed Sara would return, but as the years went by I understood that his loyalty asked for no reward, and that love comes in unexpected forms. His wish was small, as hers had been -- merely to be beside her. As for me, I already knew I would never get what I wanted."

Previous Quote

She had never realized any love save love as passion. Such love, though it expends itself in generosity and thoughtfulness, though it give birth to visions and to great poetry, remains among the sharpest expressions of self-interest. Not until it has passed though a long servitude, though its own self-hatred, though mockery, though great doubts, can it take its place among the loyalties. Many who have spent a lifetime in it can tell us less of love than the child that lost a dog yesterday.
