What is the most disgusting person you have ever met?

A colleague of mine who used to work in Shandong lived in a dormitory and usually had a good relationship. His family is from Henan, and his girlfriend works in his hometown in Henan. Once he had a problem with his girlfriend, who insisted on breaking up with him. He wanted to go back and persuade her. She had no money on her, so he asked me to borrow it. I didn't bring it with me either, but seeing that he was in a hurry, I borrowed 500 yuan from my friend. After a few years, my salary is only 1200 yuan for one month. Then he went out of thin air and never contacted me again. Although I don't have much money, I still feel sick until now. It is the most disgusting thing that has made me feel for so many years.
