My first John C. Campbell class was with Charlie and I had another later with him. He was special in many ways. My own memory of him will allways be "THE LOOK". If I was doing something wrong and glanced up he would be giving me "THE LOOK" and I knew instantly that I had to straighten up. It got so bad that even when he was behind me, out of my sight, I could feel a sensation on the back of my neck and would look behind me and find him giving me "THE LOOK". Let me echo Linda, He will be missed.
