Famous quotes containing the word door:

    While they stand at home at the door he is dead already,
    The only son is dead.

    But the mother needs to be better,
    She with thin form presently drest in black,
    By day her meals untouch’d, then at night fitfully sleeping, often waking,
    In the midnight waking, weeping, longing with one deep longing,
    O that she might withdraw unnoticed, silent from life escape and
    To follow, to seek, to be with her dear dead son.
    Walt Whitman (1819–1892)

    A door is what a dog is perpetually on the wrong side of.
    Ogden Nash (1902–1971)

    I went back to my work, but now without enthusiasm. I had looked through an open door that I was not willing to see shut upon me. I began to reflect upon life rather seriously for a girl of twelve or thirteen. What was I here for? What could I make of myself? Must I submit to be carried along with the current, and do just what everybody else did?
    Lucy Larcom (1824–1893)
