Why did my friend suddenly call me and tell me that he needed money to do research?

Ask about the details between you in detail. If he answers correctly, he is a liar. If he is close to you, go and see him. He has nothing but wine and a little money. If you borrow money, do what you can. Don't let mosquitoes bite you and tickle others! Shit, I haven't contacted your money for a long time. I'll let him go when I think you have money. When will such a person think of asking you to pay back money when he has something to do? )
