" It is hard to live alone in the dark, confusing the day and night; dropping to sleep through sheer weariness at mid-day, and rising restless in the chill of the dawn. At first Dick, on his awakenings, would grope along the corridors of the chambers till he heard some one snore. Then he would know that the day had not yet come, and return wearily to his bedroom. "

― Rudyard Kipling , The Light That Failed
