Sister is probably the most competitive relationship within the family, but once the sisters are grown, it becomes the strongest relationship.
In a way, I was incredibly proud of her (not that I had any intention of letting it show while I was beating the crap out of her).
We hang out, we help one another, we tell one another our worst fears and biggest secrets, and then just like real sisters, we listen and don't judge.

Sisters function as safety nets in a chaotic world simply by being there for each other.
You can kid the world, but not your sister.
Big sisters are the crab grass in the lawn of life.
