Friends play an important part in our lives，and although we may take friendship for granted (认为……理所当然)，we often don’t clearly understand how to make friends.While we get on well with a number of people，we are usually friends with only a very few.For example，the average among students is about 6 per person.In all the cases of friendly relationships，two people like one another and enjoy being together，but beyond that，the degree of intimacy (亲密) between them and the reasons for their shared interests vary (变化) greatly.As we get to know people，we take into account things like age，race，economic condition，social position，and intelligence.Although these factors (因素) are not of great importance，it is more difficult to get on with people when there is a marked difference in age and background.

Some friendly relationships can be kept on argument and discussion，but it is usual for close friends to have similar ideas and beliefs，the same opinions and interests.They often talk about “being_on_the_same_wavelength”．It generally takes time to reach this point.And the more intimately (密切地) involved people become，the more they depend on one another.People who want to be friends have to learn to put up with annoying habits and to stand differences.

In contrast (比较) with marriage，there are no friendship ceremonies to strengthen it between two people.But the supporting and understanding of each other that results from shared experiences and feelings does seem to create a powerful bond，which can overcome differences in background，and break down barriers (障碍) of age，class or race.
