When we don't understand each other's language, we can talk with the help of signs. A Frenchman was once travelling in England. He could not speak English at all. One day he went into a restaurant and sat down at a table. When the waiter came, he opened his mouth, put his fingers in it, and took out again. He wanted to say . "Bring me something to eat." The waiter soon brought him a cup of tea. The man moved his head from side to side. The waiter understood him and took the tea away. In a moment he came with a cup of coffee. But the man again refused it. He shook his head whenever the waiter brought him something to drink, for drinks are not food. When the man was going away, another man came in. This man saw the waiter , and he put his hand on his stomach. That was enough. In a few minutes there was a large plate of meat and vegetables on the table in front of him. So you see, we cannot understand the language of signs as well as we can understand the language of words. From this story we know  _
