What is the most shameless person you have ever met?

The most shameless thing I have ever seen is to borrow money from my neighbors for many years and go to their houses to drink every day. This happened to me. My neighbor, there are four people in my neighbor's family, who usually work to support their families. This is normal in rural areas. What is abnormal is that he always likes to borrow money, go to the grocery store and owe money, and also likes to play mahjong. His wife doesn't know how to play, but she teaches by hand and catches up with others every year. Suddenly one day, a neighbor in his forties came to my house and asked me to borrow 5,000 yuan, saying that he would buy a house in the county. I only lent him 3000 yuan at that time. Two years later, when I was building a house in the village, I went to his house to collect debts because of insufficient funds for building a house. He said glibly, nothing. I will send the money to your home tomorrow. At 7 o'clock the next night, he came. It happened that my family was having dinner. I'm glad to welcome him. After dinner, he said that he was too busy today and the money would be settled tomorrow. In a blink of an eye, the next day and dinner time. There he goes again.
