     Andy: I think being honest is the most important. Honesty is the best policy(原则). It is where a good

friendship(友谊) starts. Friends must be able to trust one another. If you don't tell the truth(事实), you

may lose your friends' trust. Good friends always trust in one another and do things honestly.

     Jim: Being generous(慷慨的) is important. It means sharing things with each other and sharing makes

a friendship grow. Being generous doesn't mean you have to give your lunch money or your clothes to

others. It means we share our ideas and feelings. By sharing them, we help our friends know us better.

      Mary: I think it's necessary for us to understand a friend. Everyone needs understanding. When

friends have a problem, talking about the problem can make it easier to solve. I must try to put myself

in my friend's place, so I can understand the problem and my friend better.
