That's Me All Over, Mable — Edward Streeter

Series of humorous letters, purportedly letters to home from a soldier in World War I, first published as a collection in 1919. According to Wikipedia: "Edward Streeter (August 1, 1891 in Buffalo, New York - March 31, 1976 in New York City) was an American novelist and journalist, best known for the 1949 novel Father of the Bride and his Dere Mable series... In all of his novels, Streeter showed remarkable perception into human nature, and a wonderfully erudite dry wit. If there is a basic theme to his main characters, it is that they are usually men who feel put-upon, but eventually realize that they are taking themselves much too seriously (Father of the Bride, Merry Christmas Mr. Baxter, and Mr. Hobbs' Vacation are typical examples.)”
