Too many people want others to be 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 friend 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 that you haven’t been honest, you may lose your friend’s trust. Good friends always count on one another to speak and act honestly.

Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes of course. Instead you have to learn how to share things you enjoy, like your hobbies and your interests. 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 the first step in solving the problem. So a friend 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 true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity, and understanding.

古诗赏析。
江城子·密州出猎
苏轼
老夫聊发少年狂,左牵黄,右擎苍,锦帽貂裘,千骑卷平岗。为报倾城随太守,亲射虎,看孙郎。
酒酣胸胆尚开张,鬓微霜,又何妨!持节云中,何日遣冯唐?会挽雕弓如满月,西北望,射天狼。
