“I… I was hoping we could discuss the birch,” Sarah began, her voice hesitant. The knife in her hand slipped from her grasp and clattered onto the counter.

Sarah kept talking, explaining about sunlight and the fence. She watched Sarah's lips move, but the words seemed to bounce off her, leaving no impression.
