Famous quotes containing the words heavy and/or oil:

    “The sin of my ingratitude even now
    Was heavy on me. Thou art so far before
    That swiftest wing of recompense is slow
    To overtake thee. Would thou hadst less deserved,
    That the proportion both of thanks and payment
    Might have been mine! Only I have left to say,
    More is thy due than more than all can pay.”
    —William Shakespeare (1564–1616)

    “To make a good salad is to be a brilliant diplomatist—the problem is entirely the same in both cases. To know exactly how much oil one must put with one’s vinegar.”
    —Oscar Wilde (1854–1900)
