Example Input: Article: Good manners are important, but you can easily make a social blunder when you visit a foreign country, because sometimes good manners in one place are bad manners in other places. Suppose you visit some friends in Mongolia and they ask you to eat with them. What kind of manners do they want you to have? They want you to give a loud "burp" after you finish eating. Burping shows that you like your food. But in some other countries, if you give a loud "burp", you are supposed to say, "Excuse me, please." In many places people like to eat together. But in some parts of Polynesia it is bad manners to be seen eating together. People show their good manners by turning their backs on others while they eat. What are manners like in an East African town? The people try not to see you. When you are visiting a friend, he may not see you at all. If you are polite, you will sit down beside him. You will wait until he finishes what he is doing. Then he will talk to you. If you visit a friend in Arabia you should walk behind other tents until you come to his tent. If you pass in front of other tents, you will be asked into each one. The people will ask you to eat with them. And it is bad manners if you say no. Manners are different all over the world. But it is good to know that all manners help people show that they want to be friends.
