““In some ways, no one is tougher on one another than sisters. Like parents, they're hyperaware of another's past foibles and faults; but, without the infinite parental capacity for love and forgiveness, they judge one another far more harshly for them. I swear there are times when they really might kill one another. Until, of course, one of them is in trouble or threatened by an outside agent, in which case they band together into an unbreakable front. Internally fractured yet externally united. The world over, it's the very definition of sisterhood.””
