We're the kind of friends who can check each other's attitudes – grateful that someone cares enough to be completely straight with us. We're the kind of friends who will keep a secret sacred and know that we can call on one another for anything – night or day. We're the kind of friends who know each other so well that we know what to joke and tease about to make each other laugh the most and what we'd never, ever tease the other one about – and why. We'll make all kinds of friends in life, but you and I will always be sister-girlfriends – that's the rarest and most precious kind of friend that there could be.
