Brothers & Sisters Season 4 Quotes

Kitty: You are gonna have to embrace your inner princess.
Rebecca: I don't have an inner princess.
Kitty: You are gonna have to get one.

From the minute my kids were born all I did was worry about them. I thought surely this will stop when they get older but no. What I worry about has changed but I'm still worrying. And what good has all this worrying done? None. With or without it my kids are doing just fine. They're happy and they're fine. I just need to learn to relax. I deserve to be happy.

Nora
