In real life, all of us have friends. We can talk to them, play and go to the cinema with them. (1) But we know that not all of them are real good friends, because simply “A friend in need is a friend indeed”.

But why are they still our friends? (2) In every one of us there is a ______ need to have friends and not to live ______ in this world. This need makes us get along with the others. On the other hand, this need keeps us searching everywhere to find new friends. But when we have found one, some time later we realize that he or she is not what we are looking for.

Everybody knows how to become a friend, but not all of them know how to become a good friend, because they don’t know what a good friend means. Some of us want to have friends just to make themselves happy, or maybe get something from others. He or she is not thinking about the others or what makes them happy. He or she is a selfish person.

Someone knows the meaning of good friendship. Someone knows how to be loyal(忠诚的) to someone, how to take care of him, and how to love him, as he is a very important person in his life. Unluckily, not everyone on the Internet wants to be a good friend as what is happening in real life. They are looking for friends, just to prove that they have a lot of friends.

About me, I’m not interested in numbers. Because I learned from the life: “Finding a real good friend is not an easy task”.
