"Once, in an early conversation I had with her about her childhood, she reminisced about a favorite doll her parents had given her when she was seven. She named her Pearl, carried her everywhere for the next four or five years, and considered her to be her best friend. The remarkable thing about Pearl was that she was able to talk and understand everything that was said to her. But Pearl never uttered a word in Grace's presence. Not because she couldn't speak, but because she chose not to."
