Famous quotes containing the words pad and/or time:

    I have known the inexorable sadness of pencils,
    Neat in their boxes, dolor of pad and paper-weight,
    All the misery of manilla folders and mucilage,
    Desolation in immaculate public places,
    Theodore Roethke (1908–1963)

    Fair Hope! our earlier Heaven! by thee
    Young Time is taster to Eternity.
    The generous wine with age grows strong, not sour,
    Nor need we kill thy fruit to smell thy flower.
    Thy golden head never hangs down
    Till in the lap of Love’s full noon
    It falls and dies: Oh no, it melts away
    As doth the dawn into the day,
    As lumps of sugar lose themselves, and twine
    Their subtle essence with the soul of wine.
    Abraham Cowley (1618–1667)
