"I am still eating," David replied, with the tone of someone who has said this many times and is still trying to sound reasonable. "I never stopped eating. I will continue to eat." So he wasn't eating casseroles and pastries. A man could live on bread and water for a long time, and he'd been hardly doing it for a couple of weeks. He would accept a slice of cheese as well if Rhiannon made faces at him, and he just made sure to avoid sitting at the table at meal times so it wasn't so obvious, out of consideration for their feelings. There were always dishes to do.
Anyway, Aderyn was coming home. His prayers for strength had been answered.
