Samuel Clemens, better known as Mark Twain, was very enamored with his daughter, Susi, and remained so up to her untimely death at age 24 in 1896. In 1875, at the age of 3, she had written her first letter to Santa Claus. As a writer and loving father, Twain, couldn't stand for his young daughter to feel like her work went unheard, so he penned the following letter to "My Dear Susie Clemens" from "The Man in the Moon" himself. Once there was a bad little boy whose name was Jim - though, if you will notice, you will find that bad little boys are nearly always called James in your Sunday-school books. It was strange, but still it was true that this one was called Jim. He didn't have any sick mother either - a sick mother who was pious and had the consumption, and would be glad to lie down in the grave and be at rest but for the strong love she bore her boy, and the anxiety she felt that the world might be harsh and cold towards him when she was gone.
