    Many people love travelling to different countries, but if you plan to go abroad, you should know how to behave properly in different situations around the world.

Most travelers enjoy meeting new people, but sometimes you can be rude without saying anything. In Russia, you should never shake hands in a doorway. And if you're travelling in Thailand, never touch people’s heads or point your feet at people. When the Japanese meet new people, they like giving business cards---but you should read the card carefully, not just put it in your pocket.

In most countries in Europe, people expect a lot of eye contact (交流) when you talk to them, but in many Asian countries, a lot of eye contact seems unfriendly. In South America, people usually stand quite close to each other when they talk, but in countries like the USA, you need to give people more personal space. Also, it's rude to interrupt(打断) Japanese people while they are talking to you. You must wait until they finish before you start speaking.

In restaurants in China, you can leave a bit of food on your plate, and it's OK to start smoking before other people finish eating, but you mustn't do these things in the UK. When in India, remember to eat with your right hand. Also avoid leaving empty bottles on the dinner table in Russia---that's bad luck.

With so much to think about, it's not surprising that many people prefer going on holiday in their own countries---or you might just decide to stay at home!
