I had a "friend" who lent me money and moved away overnight. What should I do?

Then ask yourself if he was destroyed in front of you, and you wouldn’t be sad. If you are this kind of friend in the future, you should not make friends with him. If you still feel sorry for him, your money will be worth it. Because you have not done anything irreparable, he may or may not pay you back in the future. Yes, but if you didn't save him at that time, his life might be ruined. So in general, you are not wrong. Don't use other people's faults to punish yourself. Don't be sad anymore. Maybe they are in difficulty now, but maybe they will pay you back in the future. In short, don't make it difficult for yourself. Sometimes people have to pay a price to prove something.
