What is the purpose of the loan? You don't need a guarantee to buy a house, a car or a credit card.
If you vouch for him, it is like lending him money.
You talk to him for a long time, and you usually refuse for two reasons:
1, it can be said that your family won't let you do it, and so on.
2. Ask him the purpose of the loan. You just said the risk was too high. You don't agree with him, because half of the same risk is on your side, so you won't guarantee him.
No matter how angry you are, it's a big deal not to talk to each other Such friends have nothing to make friends with.
