Patterson: Certainly. I realized that when she tears a page out of a magazine or a book, it’s not trash. It’s meaningful. She wants us to see it. Plus, she also uses some cards we gave her [with objects printed on them] when she has something to say. I remember one Valentine's Day, she had some cards out waiting for me that stated pretty clearly “Where are the goodies?”
