What do you think of British people and American people? You might think that there are no differences between the people in the two countries. After all they speak the same language, don't they? But if you ask a British or an American person, the differences are quite great.

What do British people think Americans are like? The British think Americans are very strange. They make a lot of noise and they laugh too loudly. They are rich, and they only think about money. But the British do say that Americans are kind, friendly people. They are happy to help you if you are in trouble.

What do Americans think of the British? Well, they think the British are cold and very unfriendly. They are not interested in success or in making lots of money.
