一个朋友总是需要的人吗?

还有什么能成为你的朋友吗?

朋友本身是一种利益关系，所以才会有所谓的真假朋友一说，只有能帮得上你的忙，也就是说你能从他身上获利的朋友，才被称为真正的朋友。
因此朋友没有什么真假之分，所谓的真假朋友，区别只在于你在他们眼里的价值，有些人认为你的价值足以抵偿他的付出，那么他对你的付出也就会更慷慨一点，而有些人认为你的价值不足以抵偿他的付出，那么你们之间的友谊，就会仅仅停留在名义上。
因此关键还是在于你自己，你自己的个人能力决定你在别人眼里的价值高低，而你对自己的定位则决定别人对你的期待值，这些都会影响到你交到“真朋友”的概率。
一个乞丐与上流阶层成为真心朋友的几率很小，因为他在上流人士眼中一文不值，并且乞丐所能带来的利益，也无法满足上流社会对于朋友关系的期待值，但是这个乞丐却很容易在穷哥们儿中找到莫逆之交，因为他们在彼此眼中的价值是对等的，而且一个乞丐对于朋友的期待值往往要大大低于上流阶层。
（Friends itself is a kind of benefit relations, so would have called a true friend from Monday, only can help you busy, so you can profit from his friends, was called the true friends.
Therefore no false friends, friends, the difference of the so-called true lies only in the value of you in their eyes, some people think that your value to counter his pay, so he would give you more generous, but some people think you to cover the value of his pay, so the friendship between you and will only stay in nominal.
Therefore, the key lies in your own your own personal ability decide you in the eyes of the people, and your value for their orientation of others decided to shoot the, these will affect you make "friend".
A beggar and upper-class become less chance of manysincerities friends because he is in the upper eye worthless and beggars can bring benefit, also cannot satisfy society for friends, but the beggar expectations are easy to find friends in poor buddy, because they are in the eyes of the equivalence value is, and a beggar for friends to shoot the upper-class often below.）
