     In the United States, it is not usual to telephone someone early in the morning. If you telephone early in

the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important

and requires immediate attention. So it is with the telephone calls made after 11:00 pm. If someone receives

a call during sleeping hours, he may think that it's a matter of life and death. The time chosen for the call

communicates its importance.

     In social life, time plays a very important part. In the USA guests tend to feel they are not highly regarded

if the invitation to a dinner party reaches them only three or four days before the party date. But it is not true

in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in

advance because plans which are made for a date more than a week away tend to be forgotten. The meaning

of time is not the same in different cultures that treat time differently; being on time is valued highly in

American life, for example. If people are not on time, they may be regarded as impolite or not fully responsible.

In the USA no one would think of keeping a business friend for an hour; it would be too impolite. A person

who is 5 minutes late is expected to make a short apology. If he is less than 5 minutes late, he will say a few

words of explanation, though perhaps he will not complete the sentence.
