Q. What is the correct procedure to be followed when

driving away from a house where one has spent an enjoyable luncheon or perhaps an entire weekend?

Name withheld, Somerset A. Occupants of a car should roll down all the windows and wave with their arms extended to the elbow as they go on their way. This is so much more friendly than trying to make restricted movements from within the vehicle which may easily be misinterpreted as V signs or gestures of relief. In this way they can take their lead from the late HM Queen Elizabeth, the Queen Mother, who, as her limousine glided away, would personally unwind her own window and fully unfurl her arm to wave an enthusiastic farewell to her hosts.
