    Cindy, Jerry and Mary are giving their ideas about what a good friend should be like.

    Cindy: I think a good friend should be honest(诚实).That's the most important thing and is where a real friendship(友谊) starts. If a friend isn't honest, he may lost his friends' trust.

    Jerry: I think a good friend should be generous. Here “generous” doesn't mean he has to give his friends his money or his clothes. It means he should share his ideas and feelings with his friends. So, his friends can know him better in this way.

    Mary: For me, a good friend should understand his friends. When there's something bad between him and his friends, he must put himself in his friends' place and think more for his friends.
