Sisters function as safety nets in a chaotic world simply by being there for each other.
Sisters are like cats. They claw each other all the time, but still snuggle up and daydream together.
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.
A sister is a gift to the heart, a friend to the spirit, a golden thread to the meaning of life.
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.
