Roger-t-s,You've just reminded me of the time when I shared a house with 2 medical interns. The dinner table conversation was often a detective-story type guessing game they played where one doctor would name a symptom and the other would try to guess what the disease was. Another symptom was named each time the other doctor guessed wrong.
It made me decide that I'd rather die than be treated by the male doctor, but I'd go anywhere to consult the female one. He kept jumping to conclusions very early in the game and then refused to be swayed in his decision by any of the symptoms named after that.
As for dinner time conversations - the rest of us were too busy trying to hang on to the contents of our stomachs to make polite conversation.
