In England recently three foreign gentlemen came to a bus stop and waited. About five minutes later, the bus they wanted came along. They were just going to get on when suddenly there was a loud noise behind them. People rushed onto the bus and tried to push them out of the way. Someone shouted at them. The bus conductor came rushing down the stairs to see what all the trouble was about. The three foreigners seem all at sea and looked embarrassed. No one had told them about the British custom of lining up for a bus that the first person who arrives at the bus stop is the first person to get on the bus.

Learning the language of a country isn't enough. If you want to have a pleasant visit, find out as much as possible about the manners and customs of your host country. You will probably be surprised just how different they can be from your own. A visitor to India would do well to remember that people there consider it impolite to use the left hand for passing food at table. The left hand is supposed to be used for washing yourself. Also in India, you might see a man shaking his head at another to show that he doesn't agree. But in many parts of India a shake of the head means agreement. Nodding (点头) your head when you are given a drink in Bulgaria will most probably leave you thirsty.
