A woman named Lit'tle Eva Lastname. Yes, that is the correct spelling of her first name; I know someone who knew her and it's pronounced La-TELL rather than little.
For anybody who doesn't know, Little Eva was a popular singer in the sixties, famous for her version of "The Locomotion."
it's also a character in Uncle Tom's Cabin, a saintly little white girl named Evangeline St. Claire who of course dies tragically. Little Eva has become a not very flattering term for what we might call something like a Mary Sue.
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
