People who have met several times lend you money. How could you tell me?

Like the probability of a pie falling from the sky. I've only met you a few times, and people lend you money. You must smile and say thank you.

It's irritating to encounter such a thing as not paying back the money. You can sue for it back. If you want to sue, there are no IOUs to fill in, and you can also collect chat records and transfer records to sue.
