I have no photograph of her that’s any good. I cannot even see her face distinctly in my imagination. Yet the odd face of some stranger seen in a crowd this morning may come before me in vivid perfection the moment I close my eyes tonight. No doubt, the explanation is simple enough. We have seen the faces of those we know best so variously, from so many angles, in so many lights, with so many expressions—waking, sleeping, laughing, crying, eating, talking, thinking—that all the impressions crowd into our memory together and cancel out into a mere blur. But her voice is still vivid.
