The year and a half I spent in South Africa working with Nelson Mandela on his autobiography--seeing him most every day--were extraordinarily thrilling and rewarding. (And add to that the fact that I met my wife there too.) When the project was over, I missed him terribly and stayed in touch as much as I could. With his 90th birthday approaching, I wanted to make sure that my two boys--each of whom boasts a Mandela-related middle name--saw the great man one more time. He was sunny and happy that morning, and spent most of the time entertaining my sons.
