When I was young, I knew that, somehow, I would go to Africa and live with animals. And I wanted to write books about them. I don't think I spent too much time wondering exactly how I would do it. I just felt sure that the right opportunity would somehow come. I didn't feel frustrated because I could not go a really long trip while Rusty was still alive. It would have seemed like a betrayal. And while I waited I went on learning.
