The Great Gatsby by F. Scott Fitzgerald:
I couldn’t forgive him or like him, but I saw that what he had done was, to him, entirely justified. It was all very careless and confused. They were careless people, Tom and Daisy—they smashed up things and creatures and then retreated back into their money or their vast carelessness, or whatever it was that kept them together, and let other people clean up the mess they had made. . . .
I shook hands with him; it seemed silly not to, for I felt suddenly as though I were talking to a child. Then he went into the jewelry store to buy a pearl necklace—or perhaps only a pair of cuff buttons—rid of my provincial squeamishness forever.
