Famous quotes containing the word holes:

    Why are all these dolls falling out of the sky?
    Was there a father?
    Or have the planets cut holes in their nets
    and let our childhood out,
    or are we the dolls themselves,
    born but never fed?
    Anne Sexton (1928–1974)

    A person taking stock in middle age is like an artist or composer looking at an unfinished work; but whereas the composer and the painter can erase some of their past efforts, we cannot. We are stuck with what we have lived through. The trick is to finish it with a sense of design and a flourish rather than to patch up the holes or merely to add new patches to it.
    Harry S. Broudy (b. 1905)

    But Father John went up,
    And Father John went down;
    And he wore small holes in his shoes,
    And he wore large holes in his gown.
    William Butler Yeats (1865–1939)
