My colleague asked me for money. Can she write an IOU like this?
No problem. Generally, a formal IOU is to write down the borrower, the borrower, the reason for borrowing time and the repayment time, and then sign the borrower's name. If you think the other person may not pay back the money, you'd better ask him to leave you identity information. There are many templates for IOUs. Money is the most unclear thing, and it is better to be a villain before a gentleman.
