A friend of mine saw him at the DNC Convention once. He said hi to her and she and another friend were so excited, they followed him out of the building to his car. He laughed and was very gracious and kind. They just stood there watching and waving at him as he drove away. I was so jealous.
If you get the chance, read the book "What Remains" by Carole Radziwill. She was the wife of JFK, Jr.s cousin Anthony, who passed away from cancer not long after John. Very sad, but a very good book.
