““It was late afternoon and the last remnants of the day were fading. The sky was slowly changing color, and as I watched the sun go down I remember thinking about that brief, flickering moment when day suddenly turns into night. Dusk, I realized, is just an illusion, because the sun is either above the horizon or below it. And that means that day and night are linked in a way that few things are; there cannot be one without the other, yet they cannot exist at the same time. How would it feel, I remember wondering, to always be together, yet forever apart? I know the answer now. I know what it's like to be day and night now; always together, forever apart.””
