Famous quotes containing the word century:

    She’s just a child,
    but I’m the one who’s fainthearted.
    She’s the woman,
    but I’m the coward.
    She bears that high, swollen set of breasts,
    but I’m the one who’s burdened.
    The heavy hips are hers,
    but I’m unable to move.
    It’s a wonder
    how clumsy I’ve become
    because of flaws
    that shelter themselves
    in another.
    Amaru (c. seventh century A.D.)
