Well, that’s quite different from America. I remember being probably just about 20 years when the director of Detroit Zoo asked me to call him by his first name. For us Europeans, that was something very special. With Heini Hediger, I was Mr. Professor until maybe 10 years before his death. And this was one of the few difficulties I have had since with several keepers. They called me by my first name, since they knew me since I was a small boy, and I called them with their family name. But we could solve this problem.
