Friendship is one of the greatest happiness that people can enjoy. It is very difficult to find a better way to explain friendship. A true friend finds happiness in our joy and share sadness in our grief(伤心事). During the life time, he or she is always at our side to give us his or her help and comfort.
Knowing how valuable friendship is, we should be careful in our choice of a friend. We must choose someone who has a good character, whose activities are good and who shows kindness of heart.
A true friend can always be trusted, loved and respected. If you tell a friend your secrets, he or she won't tell anyone else. Friends share each other's joys and grief. They help each other when they are in trouble, and cheer each other up when they are sad. The most important things is that a friend always understands you. In a word, when you have made a good friend, don't forget him or her.
