Have you ever heard the saying “If you want a friend, be one”?

Here is how one new teacher made friends with the girls and boys in her class on the first day of school. As the bell rang, the teacher smiled at each girl and boy. Then she said in a quiet voice, .”Good morning. How nice it is to have all of you in my class this year..I’d like to know each of you .I am sure we will enjoy working together.” Everyone felt that she meant what she said because of her sweet voice and her friendly look.

She told the girls and boys her name and wrote it on the blackboard. Then she told them some of the things she liked to do and she was hoping to do with them during the year.

Then she said to the class, “Now you know my name and the things I like and I want to know your names and the things you like. Then I will feel that I know you.”
