What should you do before you enter a house in some Asian countries?

Different countries and different people have different manners. Before entering a house in some Asian countries, it is good manners to take off your shoes. In some European countries, even though shoes are very muddy, this is not done. A guest in a Chinese house sometimes does not finish a drink to show that enough has been had. In a Malay house, too, a guest always leaves a little food. In Eng land, a guest always finishes a drink to show that he or she enjoys it.
    We should learn about the customs of other people, so that they will not think us ill-mannered. But people all over the world agree that being well-mannered really means being kind and helpful to others, especially to those older or weaker. If you remember this, you will not go wrong.
    Here are some examples of the things that well-mannered people do and do not do. They never laugh at people when they are in trouble. They are always kind either to people or animals. When peo ple are waiting for a bus, or in a post office they line up to wait for their turn. On the bus, they give their seats to older people who are standing. If they accidentally bump into someone, or get in their way, they say "Excuse me" or "I’m sorry".
    They say "Please" when making a request, and "Thank you" when they receive something. They do not sit down until other persons are seated. They do not talk too much about themselves. When they’re eating, they do not speak with their mouths full of food.
