“People lose fifty million skin cells every day. The cells get scraped off and turn into invisible dust, and disappear into the air. Maybe we are nothing but skin cells as far as the world is concerned.”

“Body cells replace themselves every month. Even at this very moment. Most everything you think you know about me is nothing more than memories.”

“The majority of people dismiss those things that lie beyond the bounds of their own understanding as absurd and not worth thinking about. I myself can only wish that my stories were, indeed, nothing but incredible fabrications. I have stayed alive all these years clinging to the frail hope that these memories of mine were nothing but a dream or a delusion. I have struggled to convince myself that they never happened. But each time I tried to push them into the dark, they came back stronger and more vivid than ever. Like cancer cells, these memories have taken root in my mind and eaten into my flesh.”

“Why do you like jellyfish so much?" I asked. "I don't know. I guess I think they're cute," she said. "But one thing did occur to me when I was really focused on them. What we see before us is just one tiny part of the world. We get into the habit of thinking, This is the world, but that's not true at all. The real world is in a much darker and deeper place than this, and most of it is occupied by jellyfish and things. We just happen to forget all that. Don't you agree? Two thirds of the earth's surface is ocean, and all we can see of it with the naked eye is the surface: the skin. We hardly know anything about what's beneath the skin.”

“Lost opportunities, lost possibilities, feelings we can never get back. That's part of what it means to be alive. But inside our heads - at least that's where I imagine it - there's a little room where we store those memories. A room like the stacks in this library. And to understand the workings of our own heart we have to keep on making new reference cards. We have to dust things off every once in awhile, let in fresh air, change the water in the flower vases. In other words, you'll live forever in your own private library.”

“With Naoko gone, I went to sleep on the sofa. I hadn't intended to do so, but I fell into the kind of deep sleep I had not in a long time, filled with a sense of Naoko's presence. In the kitchen were the dishes Naoko ate from, in the bathroom was the toothbrush Naoko used, and in the bedroom was the bed in which Naoko slept. Sleeping soundly in this apartment of hers, I wrung the fatigue from every cell of my body, drop by drop. I dreamed of a butterfly dancing in the half-light.”
