An older sister helps one remain half child, half woman.

Sisters share the scent and smells - the feel of a common childhood.

Sisters never quite forgive each other for what happened when they were five.

If you don't understand how a woman could both love her sister dearly and want to wring her neck at the same time, then you were probably an only child.

Having a sister is like having a best friend you can't get rid of. You know whatever you do, they'll still be there.

You'll always be my friend, you know to much.

A sister shares childhood memories and grown-up dreams.

Sisters may share the same mother and father but appear to come from different families.

We acquire friends and we make enemies, but our sisters come with the territory.

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.

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

Sisters are different flowers from the same garden. Sisters are blossoms in the garden of life.

Sisters remember the hair cuts and clothes our mother used to make us wear for school pictures.

Sister to sister we will always be, A couple of nuts off the family tree.

Raising kids is like getting pecked to death by a chicken!

And our favorite one is:
When sisters stand shoulder to shoulder, who stands a chance against us?
