There is a saying that two good friends must be at the same financial level; otherwise, they will be not familiar in the end. Some proponents think that it is reasonable because financial level decides friends ' live styles and personality. However, some disapprove it , including me, holding the idea that friendship is bound by two kind hearts ,but not money. Though money can affect one's life style ,personality or even thoughts sometimes .it is not related too much to make friends. And friends mean more in emotion ,not in money or other material needs. On the one hand, friendship is decided by two friends' kindness, true emotion. and same ideas on some things. It is common to see two guys become familiar and respect to each other when they share the similar thoughts at one matter and they appreciate each other. Under this condition, even people don't have same financial lever at all ,they can be friends. On the other hand,most true friends are not from the same filed and this is because that difference is one of the most important factors to people. Only differences make two ones find the spark points from each other and would like to explore the other 's world. By contrast,similarity brings about disparities, especially financial level.
