Famous quotes containing the word rivalry:

    Sisters define their rivalry in terms of competition for the gold cup of parental love. It is never perceived as a cup which runneth over, rather a finite vessel from which the more one sister drinks, the less is left for the others.
    Elizabeth Fishel (20th century)
