this friend, you are an honest, kind, grateful and helpful advocate. Your cousin is a mercenary, heartless and unjust scumbag. It is by taking advantage of your kindness, gratitude and trust that he defrauded you of your money. The most hateful thing is that such people will push their luck and be insatiable. When they hurt you, they never feel ungrateful and sorry for you. They just take it for granted. If you ask him to pay back the money, in a word, there is no such thing as a death sentence, so I will give you such a reply easily. If you are anxious again, you will come again. There are too many such people in today's society, so we should keep our eyes open and learn to say no in the future. Kindness should also have a bottom line. Learn from your mistakes and learn from them.
