      "How are you?" is a nice question. It's a friendly way that people in the United States greet each other.

But "How are you?" is also a very unusual questin. It's a question that often doesn't have an answer. The

person who asks "How are you?" hopes to hear the answer "Fine.", even if the person's friend isn't fine.

The reason is that "How are you?" isn't really a question and "Fine." isn't really an answer. They are simply

other ways of saying "Hello!" or "Hi!". 

      Sometimes, people also don't say exactly what they mean. For example, when someone asks, "Do you

agree?", the other person might be thinking, "No, I disagree. I think you're wrong …" But it isn't very polite

to disagree strongly, so the other person might say "I'm not sure …". It's a nice way to say that you don't

agree with someone.

      People also don't say exactly what they are thingking when they finish talking with other people. For

example, many talks over the phone finish when one person says "I've to go now." Often, the person who

wants to hang up gives an excuse, "Someone is at the door." "Something is burning on the stove."  The

excuses might be real, or it might not. Perhaps the person who wants to hang up simply doesn't want to

talk any more, but it isn't polite to say that. The excuse is more polite, and it doesn't hurt the other person.

      When they are greeting each other, talking about an idea, or finishing a talk, people often don't say

exactly what they are thinking. It's an important way that people try to be nice to each other, and it's also

a part of the game of language.
