      Have you ever heard of the saying," If you want a friend, be one." What does it mean? There are

many different things that you can do to make friends. You may find out what they are if you watch

someone make friends.  

      Here is how one new teacher made friends with the students in her class on the first day of the

school. When the bell rang, the teacher smiled at all the students. Then she said, "Good morning.

How nice it is to have all of you in my class this year! I want to know each of you very much. I am

sure we will enjoy working together."

      The teacher smiled, used a pleasant voice, and acted in a friendly way. She told the students her

name and wrote it on the blackboard. Then she told them something she liked to do and hoped to do

with them during the year. The students knew that she liked many of the things they liked. Everyone

felt that she meant what she said. Each of them wanted to know her better and be her friend.

      Then she let the students tell something about themselves. So they felt that the teacher knew them.

Could you make friends as the teacher did?

      How do you get to know your classmates? One way is to find out more about them. During the

break you can talk to them. You may ask them their names and the names of the schools they went to

last year. They want to know about you, too. You may tell them about your interests or your holiday

experiences. It is often easy to be friends with whom people have the same interests and play the same

games. As you talk, the others may think, "I like to do the same things you do. It would be fun to be

friends with you." 

      Remember! Just talking together in a friendly way is one good way to make friends.
