When he spoke it now, it seemed to her she had never heard a sweeter sound. 'Gwenhwyfar. Why do you weep?'
Now she must lie, and lie well, because, she could not in honor tell him the truth. She said, 'Because-' and stopped, and then, in a choking voice, she said, 'because I do not know how I shall live if you go away. "
