In love, even pain feels precious if it comes from the beloved, because cruelty is far better than total indifference. Here, the poet tenderly confesses that their complaints are merely playful teasing—an excuse to keep the conversation alive. In truth, to be noticed by the beloved, even through their torment, is treated as a profound grace and blessing.
