Both within the family and without, our sisters hold up our mirrors: our images of who we are and of who we can dare to become."
A sister is both your mirror -- and your opposite.
"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 . . ."
"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."
