There are some things about myself I can’t explain to anyone. There are some things I don’t understand at all. I can’t tell what I think about things or what I’m after. I don’t know what my strengths are or what I’m supposed to do about them. But if I start thinking about these things in too much detail the whole thing gets scary. And if I get scared I can only think about myself. I become really self-centered, and without meaning to, I hurt people. So I’m not such a wonderful human being.

I'd be smiling and chatting away, and my mind would be floating around somewhere else, like a balloon with a broken string.

Then I noticed that my shadow was crying too, shedding clear, sharp shadow tears. Have you ever seen the shadows of tears, Mr. Wind-Up Bird? They’re nothing like ordinary shadows. Nothing at all. They come here from some other, distant world, especially for our hearts. Or maybe not. It struck me then that the tears my shadow was shedding might be the real thing, and the tears that I was shedding were just shadows. You don’t get it, I’m sure, Mr. Wind-Up Bird. When a naked seventeen-year-old girl is shedding tears in the moonlight, anything can happen. It’s true.

Math is like water. It has a lot of difficult theories, of course, but its basic logic is very simple. Just as water flows from high to low over the shortest possible distance, figures can only flow in one direction. You just have to keep your eye on them for the route to reveal itself. That’s all it takes. You don’t have to do a thing. Just concentrate your attention and keep your eyes open, and the figures make everything clear to you. In this whole, wide world, the only thing that treats me so kindly is math.

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.

Ever since that happened to me, I haven't been able to give myself to anyone in this world.

I want to believe you, but if that's true, I just don't get it. Why does loving somebody mean you have to hurt them just as much? I mean, if that's the way it goes, what's the point of loving someone?
