She is your mirror....

There can be no situation in life in which the conversation of my dear sister will not administer some comfort to me. 

~Mary Montagu

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. Some days, she’s the reason you wish you were an only child. 

~Barbara Alpert
