A sister can be seen as someone who is both ourselves and very much not ourselves - a special kind of double. - Toni Morrison
She is your mirror, shining back at you with a world of possibilities. She is your witness, who sees you at your worst and best, and loves you anyway. She is your partner in crime, your midnight companion, someone who knows when you are smiling, even in the dark. She is your teacher, your defense attorney, your personal press agent, even your shrink. - Barbara Alpert
In the cookies of life, sisters are the chocolate chips... *M&M*
