If we want to deal with the association（交往） between boys and girls properly, here are some “dos and don’ts” for you to follow.

Keep a normal and healthy state of mind. Our schools and classes are made up of boys and girls. It is very natural for the boys and girls to make friends with each other. We should make as many friends as possible. We should keep in touch with the other sex（性别） in public instead of in secret.

Don’t be too nervous or too shy. If you are a shy person, you can also find a way out. First of all, you can make friends with the students who have the same interest and hobby as you. As both of you have much in common, you may have much to talk about. If you keep doing like that, little by little, you will gladly find you are also as free to express yourself as others.

Don’t fall into the ditch of early love. The boys and girls at adolescence（青春期） are rich in feeling. They are easy to regard the friendship as a sign of love and fall in love with each other at an early age. In my opinion, early love is a green apple that can’t be eaten. An apple won’t taste sweet until it is fully ripe. Boys and girls at middle school are too young to carry the heavy duty of love. Do keep out of early love.
