There is a person because of the big number.As far as friends,the number or time how long he kept the relation as a friend are meaningless. The meaning of friends is the quality.A friend must have an effect on his friend.To do so we must make effort to rise to a higherlevel for his friend and they must educate each other, just like one on one English practiice. Both of them must make progress at the same time. So an idleperson should not approach valuable person. As I want be a friend of a nice person I consider that I'm valuable to him before I comr close to him.
