““We are contemplating the nature of desire,” said Han Fei-tzu. “Whose desire?” she asked. “And for what?” My desire for your bones to heal and become strong, so that they don’t snap at the slightest pressure. So that you could stand again, or even raise an arm without your own muscles tearing away chunks of bone or causing the bone to break under the tension. So that I wouldn’t have to watch you wither away until now you weigh only eighteen kilograms. I never knew how perfectly happy we were until I learned that we could not stay together. “My desire,” he answered. “For you.””
