Jay Gatsby, "The Great Gatsby".

“He smiled understandingly—much more understandingly. It was one of those rare smiles with a quality of eternal reassurance in it, that you may come across four or fives times in a lifetime… Precisely at that point it vanished and I was looking at an elegant young roughneck, a year or two over thirty, whose elaborate formality of speech just missed being absurd. Some time before he introduced himself I'd got a strong impression that he was picking his words with care.” (48)
