The first time I saw Jim Wooten I really understood him. He was a great TV news reporter. When he was reporting in Rwanda, one heartbreaking moment made a deep impression on me. When the camera showed all of the children who were dying, suffered from terrible diseases, Jim ended his piece by saying that when he got home, the first thing he was going to do was to put his arms around his own children. Then I realized that he was different, that he didn’t fall into any of the modern television-news tricks, that he was not giving us any awful, artificial(假的) television-journalist reports out of（出于) pity. Instead, I was watching a real reporter with a gift(天赋) for both words and slight differences.

Then I read his book, We Are All the Same, about his friendship with Xolani Nkosi, a South African boy who became the international spokesman for AIDS(艾滋病). It is about the friendship between Wooten and a black child who was ten years old and already dying of AIDS. It is also a book about a great teacher and his student. But the teacher－the one with real wisdom and understanding about life－is the little boy, not the journalist. And, finally, it’s about a love story of Gail Johnson, Nkosi’s white mother who does her best to save the boy, and their love for each other. When reading the book, I felt touched from time to time.
