Famous quotes containing the word rain:

    “... his voice and hands,
    Within whose warm spring rain of loving care
    Each dwells some twenty seconds. Now, dear child,
    What’s wrong, the deep American voice demands,
    And, scarcely pausing, goes into a prayer
    Directing God about this eye, that knee.”
    —Philip Larkin (1922–1986)
