     Everyone needs friends. Friends bring us happiness and hope in our lives. But the ability to make friends changes from person to person. To some people, making friends is easy, and to others it’s very difficult.

     Making friends is a skill, and the first thing is to know how to get on with others.

     If you have trouble in making friends, maybe I can tell you how to do it.
