I borrowed 50,000 yuan from my childhood friend and we agreed to pay it back in three months.

Three years passed, and he bought a new car and a new phone, but he never mentioned repaying the money.
I couldn’t help but urge him: Brother, can that 50,000 be paid back to me first?
He said: What are you急 about? With our relationship, are you afraid I’ll run off?
I said: It’s not that I’m afraid you’ll run off—I truly don’t have money to pay the rent.
He was silent for a moment, then said: Then let me teach you a way. Go borrow it—borrow 50,000—and use it to pay the rent first. Anyway, Jiebei’s interest is low. I’ll pay you back the principal later; you’re only losing the interest.
After I heard it, I just stood there in a daze for a long time.
Then I really borrowed 50,000.
But not to pay the rent.
I transferred it to him and wrote in the note: This is the second loan to you. When will you repay the first one? The second loan will start accruing interest from the time you repay the first one.
He received the money and replied with one word: ruthless.
Three days later, he repaid the first 50,000.
As for the second one—up to now, he still hasn’t repaid it.
So the moment you lend money, you’ve already lost. Only the person who dares to speak up wins.
