Drawing Does not Help
A Frenchman was travelling in Italy. He could not speak any Italian and it was extremely difficult for him to make himself understood. Once on a rainy day he entered a restaurant to have lunch, for he was hungry and thirsty.
He wanted to order some mushrooms, which he was very fond of. So he called up the waiter and ordered a dish of mushrooms in French. The waiter could not understand a word. What was the poor Frenchman to do?
Suddenly a brilliant idea struck him. " If I show him the picture of a mushroom he will certainly understand what I want, " he said to himself. So he took a piece of paper and a pencil out of his pocket and drew a picture of a mushroom on it. The waiter looked at it, nodded his head and ran out of the room. A few minutes later he came back with an umbrella.
