P on person's experience

Although learning something by yourself is good, learning something from other's experience is also good. Sometimes, some experience you don't want to face by yourself, but you also want to learn from them. I have one experience from my father. He taught me about borrowing and lending money. The story is his old friend, who he never met for a long time, need some money and asked him for help. But he didn't lend him money because his father taught him that if you don't want to break your friendship, don't lend or borrow money from friends. Since if you lend someone's money and he/she didn't pay you back, you will disappoint. Similarly, if you borrow someone's money and you can't pay him/her back, he/she will disappoint. Then, your relationship will be unstable and may be you can't be friend anymore. He also said that maybe it's hard to refuse someone's asking, but it's harder to keep your friendship after you lend or borrow money from friends. However, if you are very close to your friends, you can lend them money if you want to. I think it's a good experience, which you may be can't ask anyone but your relatives or close friends because it looks like a small problem. But, don't forget that it's delicate.
