An English couple have a child

After the birth, medical tests reveal that the child is normal, apart from the fact that it is German. This, however, should not be a problem. There is nothing to worry about. As the child grows older, it dresses in lederhosen and has a pudding bowl haircut, but all its basic functions develop normally. It can walk, eat, sleep, read and so on, but for some reason the German child never speaks. The concerned parents take it to the doctor, who reassures them that as the German child is perfectly developed in all other areas, there is nothing to worry about and that he is sure the speech faculty will eventually blossom. Years pass. The German child enters its teens, and still it is not speaking, though in all other respects it is fully functional. The German child's mother is especially distressed by this, but attempts to conceal her sadness. One day she makes the German child, who is now 17 years old and still silent, a bowl of tomato soup, and takes it through to him in the parlour where he is listening to a wind-up gramophone record player. Soon, the German child appears in the kitchen and suddenly declares, "Mother. This soup is a little tepid." The German child's mother is astonished. "All these years," she exclaims, "we assumed you could not speak. And yet all along it appears you could. Why? Why did you never say anything before?" "Because, mother," answers the German child, "up until now, everything has been satisfactory."
