Famous quotes containing the words card and/or reader:
“In the game of Whist for two, usually called Correspondence, the lady plays what card she likes: the gentleman simply follows suit. If she leads with Queen of Diamonds, however, he may, if he likes, offer the Ace of Hearts: and, if she plays Queen of Hearts, and he happens to have no Heart left, he usually plays Knave of Clubs.”
—Lewis Carroll [Charles Lutwidge Dodgson] (18321898)
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (18171862)
