To have a loving relationship with a sister is not simply to have a buddy or a confident — it is to have a soulmate for life.
Sisters function as safety nets in a chaotic world simply by being there for each other.
Sisters are the people we practice on, the people who teach us about fairness and cooperation and kindness and caring — quite often the hard way.
Sisters may drive you crazy, get into your stuff, and irritate you. However, if anyone else dares say so, a sister will defend you to the death.

You keep your past by having sisters. As you get older, they're the only ones who don't get bored if you talk about your memories.

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

Sisters are like flowers in the garden of life.
A sister is a gift to the heart, a friend to the spirit, a golden thread to the meaning of life.
Sisters are angels who lift us to our feet when our wings have trouble remembering how to fly.
A sister is both your mirror – and your opposite.
A sister is a little bit of childhood that can never be lost.
Is solace anywhere more comforting than in the arms of a sister?
Sisters are for sharing laughter and wiping tears.
A sister is both your mirror — and your opposite.
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.
Sisters are different flowers from the same garden.

Help one another, is part of the religion of sisterhood.
