|“||You know, you're wasting your time, Stefan. Let me tell you a little story. When we moved to Dallas, Caroline joined a book club. You know, it seemed like a good idea. At first, it was once a week, And then it was twice a week, then she started coming home later and later. So one night I followed her. The point is this, there was no book club. Turns out, she'd park her car down by the river so she could cry, alone. And then something happened. She stopped making excuses to be somewhere else, and the girls and I stopped being a placeholder. And we became her life.||”|
