A young married couple who lived near a famous golf-course were entertaining an elderly aunt from the depths of the country.
Well, Aunt Mary, how did you spend this afternoon? asked the hostess on the first day.
Oh, I enjoyed myself very much, replied Auntie with a beaming smile, "I went for a walk across the fields. There seemed to be a great many people about, and some of them shouted to me in a most eccentric manner, but I just took no notice. And, by the way," she went on, "I found such a number of curious little round white things. I brought them home to ask you what they are."
