Dish Licking?

Bryant, a youngster about four years old, loved having ice cream after dinner every evening. He would sit on his mother's lap and have a small bowl for dessert.

Unfortunately, he developed the habit of licking the bowl afterwards to "make sure he got it all". This went on for a while, much to his mother's chagrin. Finally, trying to tactfully hint that it was not such a great idea, she said, "You know, when I was your age, my mother said that licking my dish was a VERY impolite thing to do."
