Friendship is very important in our life. Life without friends is just like the winter without sunshine. We can share our hapiness and sorrow with our friends at any time. Friends can help us get out of trouble. So develop a good friendship is necessary for us . I think we should be kind and honest to our friends if you want them to treat you like this . What's more ,we should think their interest above ours . Only in this way can we strengthen our friendship.
