    Everyone needs friends. But how do you find real friendship and keep it?

    The American writer Sally Seamans tells young students some smart ways to find friends. Sally says founding friendship is just like planting a tree. You plant the seed (种子) and take care of it to make it grow.

    First, you should choose a friend. What makes a good friend? It is not because a person has money or good looks. A good friend should be kind and patient. For example, if you have a bad day, a good friend could listen to your complaints (抱怨) and do his or her best to help you. To make a friend, you can't be too shy. You should make each other happy and share your lives.

    But things can not always be happy. Even the best friends have fights. What should you do when you have a fight with your friend? You have to talk to him or her. When there is no one around, have a good talk. If he or she doesn't want to talk, you can write a letter.

    There are three steps to be friends again:

    Tell him or her how you are feeling, say what your friend did wrong and talk about why you did this or that. Remember that friendship is one of the most important things in your life.
