A high school history teacher once told us, “If you make one close friend in school, you will be most fortunate. A true friend is someone who stays with you for life.”      teaches that he is right. Good friendship is just not easily   .
It is possible that we simply do not stay in one place long enough for a true friendship to    . However, there can be      disagreement in the need for each of us to think carefully about what kind of friendship we want.
To most of us,     are considered very important, but we need to make it clear in our minds what kind of friendship we want. Are they to be close or      at arm’s length? Do we want to     ourselves or do we want to walk on surface(表面)? For some people, many friendships on the surface are      enough and that’s all right. But at some point we need to make sure that our      are the same as our friends’ expectations. The sharing of     experiences including our tears as well as our dark dreams is the surest way to       friendships. But it must be done slowly and     only if there are signs of interest and action     .
What are some of the    of friendship? The greatest is the attraction to expect too much too soon. Deep relationships     time. Another “main difficulty” is the selfishness to think one “      ” the other, including his time and attention.   , friendships require actions in return. In other words, you must give as      as you take. Finally, there is a question of taking care of. Unless you spend      time together, talking on the phone, writing letters, doing things together, friendships will die     .
