I always think a network of communication and exchange of ideas is very important. And I’m an old-fashioned man so I think the direct contact and knowledge of colleagues helps very much in solving problems or getting exchanges or so on. And I always considered it as one of my tasks, when a colleague visited us in Frankfurt or before in Zurich, that I myself guided this colleague through the zoo. And usually some exchange is resulted or some ideas I could give the colleague or he could, I always asked him, you don’t have to tell me how good our exhibits are, but you have to tell me what we could do better. And so we learned really. And of course, this cooperation is very much supported by these and all meetings.
