Famous quotes containing the words counter, machine and/or models:

    I’d take the bus downtown with my mother, and the big thing was to sit at the counter and get an orange drink and a tuna sandwich on toast. I thought I was living large!... When I was at the Ritz with the publisher a few months ago, I did think, “Oh my God, I’m in the Ritz tearoom.” ... The person who was so happy to sit at the Woolworths counter is now sitting at the Ritz, listening to the harp, and wondering what tea to order.... [ellipsis in source] Am I awake?
    Connie Porter (b. 1959)

    All day long the machine waits: rooms,
    stairs, carpets, furniture, people
    those people who stand at the open windows like objects
    waiting to topple.
    Anne Sexton (1928–1974)

    The greatest and truest models for all orators ... is Demosthenes. One who has not studied deeply and constantly all the great speeches of the great Athenian, is not prepared to speak in public. Only as the constant companion of Demosthenes, Burke, Fox, Canning and Webster, can we hope to become orators.
    Woodrow Wilson (1856–1924)
