Famous quotes containing the word table:

    But hospitality must be for service, and not for show, or it pulls down the host. The brave soul rates itself too high to value itself by the splendor of its table and draperies. It gives what it hath, and all it hath, but its own majesty can lend a better grace to bannocks and fair water than belong to city feasts.
    Ralph Waldo Emerson (1803–1882)

    Many a time I have seen my mother leap up from the dinner table to engage the swarming flies with an improvised punkah, and heard her rejoice and give humble thanks simultaneously that Baltimore was not the sinkhole that Washington was.
    —H.L. (Henry Lewis)

    The salt person and blasted place
    I furnish with the meat of a fable;
    If the dead starve, their stomachs turn to tumble
    An upright man in the antipodes
    Or spray-based and rock-chested sea:
    Over the past table I repeat this present grace.
    Dylan Thomas (1914–1953)
