At the Berlin Wall, the East German guards were still standing at some of the old guard posts, and Mr. Hope started a conversation back and forth through a couple of holes in the wall. They exchanged hats, and took photos of Mr. Hope wearing an East Berlin guard's hat. It was very impromptu, and you could tell Mr. Hope was really enjoying it. I remember it was probably in the low 80s that day, the sun was shining brightly, and it was warm enough that just walking around you'd work up a sweat. Mr. Hope had his jacket on, collar turned up—you could tell he was on the chilly side, just like any other old geezer.
Mrs. Hope looked out for him quite a bit; she could tell when he was tiring, and she would take him away and get him the rest he needed. But when it was showtime, he was always 100 percent.
