"I had taken one of my wealthy friends with me. She said, 'Don't you just feel guilty? Don't you just feel terrible?' I said, 'No, I don't. I do not know how me being destitute is going to help them.' Then I said when we got home, 'I'm going home to sleep on my Pratesi sheets right now and I'll feel good about it.' "
