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

We are sisters. We will always be sisters. Our differences may never go away, but neither, for me, will our song.

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.

Every articulate family ... generates its own stories, explanations and myths to illuminate the differences in temperament and talent among its children, the lines of allegiance and influence between parent and child.

A sister is both your mirror - and your opposite.
