First, it is easy to find abundant sources that make you entertaining and fun around you, but it is hard to find a true friend who can give you a hand when you are in need. What do you do when you are bored? You probably turn on the computer and play games or surf internet. Also, you can go outside play some sport. You do not need to have friend just for fun because there are many other activities to entertain you. However, what can you do, when you are in need of something that you cannot do it without some help from others? That is when you need a friend who can give you help when you need it. But when you need help, you need someone to help you. Like, in a school, you are absent one day, and teacher is going to discuss important materials for next test in class. No one really can help you to get that information even parents cannot do this for you. On the other hand, your good friend in your class can help you to have the information. He or she help you to understand the material and give you a note to copy. This shows that it is more important to select a friend who can help you when I need it whereas there are a number of source which can replace a pal whom you can have fun with.
