Everyone wants to own the friendship, because without a friend, the world is like a desert. The
friendship is thought very important. Too many people want others to be their friends, but they don't
give friendship back. That is one of the causes why some friendships don't last very long. To have a
friend, you must learn to be one. You must learn to treat your friend the way you want your friend to
treat you. Learning to be a good friend means learning the following rules.
Honesty (诚实) is where a good friendship starts. Friends must be able to trust (信任) one another.
If you don't tell the truth, people usually find out, and you may lose your friend's trust. Good friends
always trust in one another to speak and do things honestly.
Generosity means sharing (分享) and sharing makes a friendship grow. You don't have to give your
lunch money or your clothes, of course. Instead you share your ideas and feelings. These can be valuable
(宝贵的) to a friend. They tell your friend what is important to you. By sharing them, you help your friends
know you better.
Sooner or late everyone needs understanding and help with a problem. Something may go wrong at
school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in
solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your
friend's place, so you can understand the problem better.
No two friendships are ever exactly alike. But all true friendships have three things in common. In fact,
good friendship will just not easily last. That is to say, you must give as much as you take, or friendship will
die away.
