Just say it, I'm listening

There are three questions given in this final exam.
I choose this question for writing.

...................................................

Everyone needs friend. No matter how successful you are. If you live without frienship, the life would be dull and boring.
A friend, like a mirror, represents a world for us. People say that, "At home, you rely on your parents. Away from home, you rely on your friends." It shows the friendship is necessary for human being. When you are sad, and the things are going to bad, a friend will help you make it though. Friendship is a wonderful thing and is vital for personal growth and success. For example, a quote says, "A friend is in need and a friend is indeed." It also means the importance of choosing friends. A true friend can comfort you even you are in the worst situation. Even only a cheerful smile can brighten you up. Moreover, you can extend your life from different friends. For an instance of mine. I have a friend who is good in cooking thus I can get some about cooking information from her often.
Friends can not only stay with you but also make your life rich and colorful. All of us can not without friends because it is an interdependent world, and therfore everyone all needs friendship in life so that you can live happier in the society.
