Famous quotes containing the words head and/or read:

    It is comforting when one has a sorrow to lie in the warmth of one’s bed and there, abandoning all effort and all resistance, to bury even one’s head under the cover, giving one’s self up to it completely, moaning like branches in the autumn wind. But there is still a better bed, full of divine odors. It is our sweet, our profound, our impenetrable friendship.
    Marcel Proust (1871–1922)

    Main Street was never the same. I read Gide and tried to
    translate Proust. Now nothing is real except French wine.
    For absurdity is reality, my loneliness unreal, my mind tired.
    And I shall die an old Parisian.
    Conrad Kent Rivers (1933–1968)
