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.
Through thick and thin, my sister is always by my side. Grateful for her constant support.
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.
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.
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.
