When you wave to a friend, you are using body language. When you smile at someone, you mean to be friendly. When you put one finger in front of your mouth, you mean "be quiet.''
Yet, people in different countries may use different body languages.
Once an Englishman was in Italy. He could speak little Italian. One day while he was walking in the street, he felt hungry and went into a restaurant. When the waiter came, the Englishman opened his mouth, put his fingers into it and took them out again and moved his lips. In this way, he meant to say, "Bring me something to eat." But the waiter brought him a lot of things to drink, first tea, then coffee, then milk, but no food.
The Englishman was sorry that he was not able to tell the waiter he was hungry. He was ready to leave the restaurant when another man came in. The man put his hands on his stomach, and this body language was good enough for the waiter. In a few minutes, the waiter brought him a large plate of bread and meat.
Finally the Englishman had his meal in the same way.
