In choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair weather friends. They will be with you as long as you have money or luck, but when you are down, they will run away. How do I know when I have found a good friend I look for certain qualities of character, especially understanding, honesty and reliability.
Above all else, I look for understanding in a friend. A good friend tries to understand how an-other person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person’ s place, and he tries to think of ways to be helpful. He is also a good listener.
At the same time, however, a good friend is honest. He does not look for faults in others. He notices their good points. In short, a friend will try to understand me and accept me.

A. always point out each other’s mistakes
B. be helped with money
C. understand each other’ s feelings
D. have money or luck
