| Different countries and people have different manners. Here are some examples. If you visit a Chinese family. You should knock at the door first. When the door opens, you should not move before the host says "Come in, please." Before coming into the house in Japan, it is good manners to take off your shoes. In European countries, even if your shoes are very dirty, this is not done. In Britain, a guest always finishes the drink or the food to show that he enjoys it. This will make the host very pleased. | |||||||||||||||
