“Sisters are made by living everyday with each other and wearing each other down until the rough spots are smooth. They're made by sharing secrets you'd never tell mom, and out of doing things for each other just because you feel like it, not because you have to. I guess you could say sisters are 'grown,' not manufactured, in a very special place called a family.”

“To the outside world we all grow old. But not to brothers and sisters. We know each other as we always were. We know each other's hearts. We share private family jokes. We remember family feuds and secrets, family griefs and joys. We live outside the touch of time.”

“You see, we are here, as far as I can tell, to help each other; our brothers, our sisters, our friends, our enemies. That is to help each other and not hurt each other. ”

“I'll bet you anything you like that half an hour after they have met, they will be calling each other sister.Women only do that when they have called each other a lot of other things first.”

“If I do find out the Secret,I won't be able to tell it to you-you know that right?And that doesn't mean I don't trust you.It's just because I can't.Sometimes even best friends have to keep secrets from each other."-Cass”

“Remember that day you said you loved me? Remember that? See, you could do that because you're basically a sane person, who grew up in a loving, sane family. You could take a risk like that. But in my family we didn't go around saying we loved each other. We went around screaming at each other. So what do I do, when you say you love me? I go and undermine it.”
