Nelson Mandela once said "I can't help it if the ladies take note of me; I'm not going to protest."

Nelson Mandela was just a human being, a person like other people, and everyone relaxed. Within a minute, that sort of thing about the leader and the lead, the gap was closed, and that's a rare thing.

Nelson's Mandela own sense of himself was a very humble reading, [different] from how the world read him. And, quite often, you had the sense that he was not comfortable with all the accolades that would be.
