He does not talk or laugh loudly in public. However, different countries have different manners. When you enter a house in some Asian countries, it is good manners to take off your shoes. In European countries, even though shoes sometimes become very dirty, this is not done. In Japan, the guest and host bow each other. But in some other countries they only nod or shake hands. A guest in a Chinese house never finishes a drink. He leaves a little to show that he has had enough. In England a guest always finishes a drink to show that he was enjoyed it. But no matter how different the manners are, people all over the world agree that good manners really mean to be kind and helpful to others, especially those older or weaker than ourselves. If you remember this, you will not go very far wrong.
