People need friends. Friendship plays an important role in our lives and studies. Friends help each other. They trust each other. They share their joys and sorrows. Friends do not place their interests above others'. We don't lie to our friends. We mustn't make friends with someone because we need his help. If we find a friend in trouble, we do our best to help them. A friend in need is a friend indeed. As the famous saying goes - take care of friends, cherish the friendship, and you will benefit for life.
