She had very much looked forward to a word in private with him. But she forgot, as she usually did, the silence that always came between them in these latter years, whenever they found themselves alone.The queer sensation in her chest, however, was all too familiar, that mix of pleasure and pain, never one without the other.She could have done without those feelings. She would have happily gone her entire life never experiencing the pangs of longing and the futility of regret. He made her human—or as human as she was capable of being. And being human was possibly her least favorite aspect of life.
