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

some friendships don't last 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 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 out. If a friend finds out you haven't been honest, you may lose friend's trust. Good friends always count on one another to speak and act honestly.

     Generosity means sharing and sharing makes a friendship grows. You do not have to give your lunch

money or your clothes. 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 better.

     Sooner or later 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 later.

     No two friendships are very 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.
