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 over for the others.
The desire to be and have a sister is a primitive and profound one that may have everything or nothing to do with the family a woman is born to. It is a desire to know and be known by someone who shares blood and body, history and dreams.
