     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 along with others.

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

     ★Realize your own good points. You have skills and talents that others will like.

     ★Believe that you are a good person and have something nice to share with others.

     ★Be humorous. Learn to laugh at yourself and your weakness. Remember to smile to others.

     ★Respect the others. Everyone has his own idea. Learn how to listen to others' ideas without trying to

make them accept yours.

you can do to show kindness. Open the door for someone. Wave to a friend and so on.

someone who will understand you.
