The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England, people shake hands when they meet each other for the first time. Also, most English men will open a door for a woman or offer their seat to a woman, and so will most Americans. Both in England and in America promptness(准时) is important. That is, if a dinner invitation is for 7 o’clock, the dinner guest either arrives close to that time or calls up to explain his delay.
