THE DIFFICULTIES OF A FOREIGN LANGUAGE.

There are numerous anecdotes about the difficulties of people travelling in foreign countries without knowledge of the language of that country. Here’s the story of a Frenchman travelling in the United States who, while eating in a restaurant, wished to order some mushrooms. Unable to make himself understood, he asked for a pencil & paper & carefully drew a picture of a mushroom. His drawing, however, was not too good, for the puzzled waiter returned in about ten menu not with an order of mushrooms, but with a large man’s umbrella. Another similar story concerns two Americans travelling in Spain. They were both unable to speak a word of Spanish & one day, while eating in a restaurant in a small village, they were having considerable difficulty in explaining to the waiter what they wanted. One of them wanted a glass of milk. The waiter seemed unable to understand.
Finally, on the back of the menu the man drew a picture of a cow. The poor waiter, however, still seemed puzzled. Finally he left & was gone from the restaurant for half an hour or so. He returned very pleased with himself. There were two tickets for a bullfight in his hand.
