When you talk yourself, you think how witty, how original, how acute you are; but when another does so, you are very apt to think only - What a crib from Rochefoucauld!
Poor people know poor people, and rich people know rich people. It is one of the few things La Rochefoucauld did not say, but then La Rochefoucauld never lived in the Bronx.
Yes, well, let me tell you that if nobody had ever learned to quote, very few people would be in love with La Rochefoucauld. I bet you I don't know ten souls who read him without a middleman.
