I would say what was always on her[Harper Lee] mind was the stories she had to tell, and the story was pretty obvious in "To Kill A Mockingbird," maybe a bit - little bit less obvious and more obscure in "Go Set A Watchman."

On average, once a month for the last 10 years since her [Harper Lee] stroke, we have sat and talked and told stories and exchanged insults... Which she loves. I think one secret to our friendship was I did not treat her like a marble woman, and my wife - I joked with her, and I joked with her, and that was the sort of contours of our friendship.

Harper Lee was legendarily private. I've never known such a private woman in my life. It's no surprise that she left Monroeville, a gossipy little southern town where everybody wants to know everybody's business, and went to the most anonymous city in America.

As a matter of fact, I constantly tell audiences all over the world that the single greatest icon of American culture from the publication of "To Kill A Mockingbird" was that novel so that if we say, what conversation can we have that would lead us on a road of tolerance, and teachers have decided that if you're going to teach values in a school in America, the answer that American teachers at all kinds of schools have come up with, just let Harper Lee teach "To Kill A Mockingbird." And then all the teacher has to do is stand back and guide the discussion.
