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.

We are each other's reference point at our turning points.

Comparison is a death knell to sibling harmony.

From the psychological jousting between sisters in the early family arena emerge the first tentative boundaries of their personalities.

What surprised me was that within a family, the voices of sisters as they're talking are virtually always the same.

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.
