My another senior researcher who has already graduated from the university had introduced my senior researcher a girl to have sexual intercourse with. But, a strange thing happened after he met her. She urged him to invest his money. Because he had already known that it is a kind of pyramid selling, he avoided to be deceived by her.
She had been deceived by someone in the same way as this. So, her main purpose was not to have sexual intercourse with him but to regain the money she lost by deceiving my senior researcher.
We have to be careful of those who approaches us without clear reasons.
