Famous quotes containing the words lights and/or signal:

    Thus while I sit and sigh the day
    With all his borrow’d lights away,
    Till night’s black wings do overtake me,
    Thinking on thee, thy beauties then,
    As sudden lights do sleepy men,
    So they by their bright rays awake me.
    Sir John Suckling (1609–1642)

    Certainly the effort to remain unchanged, young, when the body gives so impressive a signal of change as the menopause, is gallant; but it is a stupid, self-sacrificial gallantry, better befitting a boy of twenty than a woman of forty-five or fifty. Let the athletes die young and laurel-crowned. Let the soldiers earn the Purple Hearts. Let women die old, white-crowned, with human hearts.
    Ursula K. Le Guin (b. 1929)
