Whereas in Heidelberg, I really had to do everything and I really mean everything. It started that I lived on the zoo’s ground. By the way, the only time I ever lived on the zoo’s ground. I wouldn’t like to do it for a longer time. And it started that I went out to the field to take in grass, to distribute the grass, with the help of keepers, of course, in the zoo, distribute food. And finally in the evening to count the monies that came in and even to pile up the dung in the evening, because nobody else was allowed in Heidelberg to pile up dung otherwise. So I really learned a lot during these two periods I replaced the Heidelberg Zoo director and I esteemed this very much.
