When British people meet each other for the first time, they say "How do you do?" and hands. Usually they do not shake hands when they just meet or say goodbye. But they shake hands after they haven't met for a long time.

Last year a group of students went to England for a holiday. Their teacher told them that the English people shake hands. So when they met their English friends at the station, they kept their hands their backs. The English students had 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.
