Klaus waited for my arrival. I arrived around 3 p.m. and he invited me to have tea with him. He took the time to suggest restaurants and cafes around his place. The first day he also gave me both a map of Berlin and a tutorial on how the system operates. When I had any questions, he would answer it, and I had too many. Klaus is an excellent host and likes to talk and know about his guests. I thank him for allowing the opportunity to get to know more about his great country. I enjoyed our chats very much _and learned a good deal.
