" 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. "
― Haruki Murakami , The Wind-Up Bird Chronicle
