A Rose by any other name

My mother was asked to see a consultant for some extra tests at Southampton General Hospital. This was arranged for out of clinic hours, i.e. early evening. We have an unusual surname; in fact there is no other family that we know of worldwide with this name spelt in this particular way. When my mother met the consultant he said he was surprised as a new member of staff from Germany ad the same surname but spelt slightly differently. He gave his first name. Later that evening my father collected my mother from the hospital and as they entered our house the telephone rang. My mother answered the phone. It was someone asking for a person with our surname, but not us. He was trying to find the phone number for the man from Germany who worked at the hospital. My mother said, "No he doesn't live here, but I can tell you where you can find him at his place of work." !!!!
