     Before you go to another country, it's great helpful if you know the language and some of the customs

of that country.

     When people meet each other for the first time in Britain, they say "Hello" or "Nice to meet you" and

shake hands. Usually they don't shake hands when they just meet or say goodbye. But they shake hands

after they haven't met for a long time or when they'll be away from each other for a long time.

     Last year a group of German students went to English for a holiday. Their teacher told them the English

people hardly shake hands. So when they met their English friends at the station, they kept their hands

behind their backs. The English students had learned that the Germans shake hands as often as possible,

so they put their hands in front and got ready to shake hands with them.It made both of them laugh.
