the only song that my mother would let louisa sing to me as a child : go to sleep my darling , its time to rest your head , the sun is calling it a day you too should go to bed , the sleepy sun is sinking , into its bed out west , so you should go to sleep now too i think that would be best i hummed the tune over and over , a broken record trying to hypnotize myself into a calmed trance as i moved .
