     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.

sure we'll 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

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

her friend.
