Although friends should help each other, borrowing money is very nerve-racking. Borrow, afraid not to return; Don't borrow, hurt feelings. Therefore, students can borrow if they have a good relationship, but they can't borrow more. If you pay it back, you can lend it to him next time (it is better to borrow less next time). If you don't pay him back, just pay for him. Sometimes people who like to borrow money should be careful, they may have bad living habits!
