     Too many people want others to be their friends, but they don't give friendship back. That is

why some friendships do not 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 treat you. Learning to be a good friend

means learning three rules. Be honest; be generous; be understanding.

     Honesty is where a good friendship starts. Friends must be able to trust one another. If you do

not tell the truth, people usually find it out. If a friend finds out that you haven't been honest, you

may lose your friends' trust. Good friends always believe in one another as they always speak and

act honestly.

     Generosity means sharing, which makes a friendship grow. People do not have to give lunch

money for clothes, of course. Instead you have to learn how to share things you enjoy, like your

hobbies and your interest. Then, naturally you will want to share your ideas and feelings. These

can be very valuable to a friend. They tell your friend what is important to you. By sharing them,

you help your friend know you better.

     Sooner or later, every one 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.

If you plan to keep your friends, you must practice honesty, generosity, and understanding.
