There are three infallible ways of pleasing an author, and the three form a rising scale of compliment: 1, To tell him you have read one of his books; 2, To tell him you have read all of his books; 3, To ask him to let you read the manuscripts of his forthcoming book. No. 1 admits you to his respect; no. 2 admists you to his admiration; No. 3 carries you clear into his heart.
—Mark Twain, American writer and journalist
