Anybody see World News Tonight last night (Monday)? They did a very nice tribute to Peter, including a bit showing his aforementioned ability to relate to children.
I watched the show with a friend. I know it's customary for them to talk of someone in superlatives when they die, but watching his career explained to us in detail, we were just in awe of his ability, drive, integrity, friendliness, humor and passion for his work.
