How to send a friend circle to borrow money and not pay it back?

If you don't pay back the money, you can send a circle of friends with the following sentence:

1, the lent money was wasted and the previous friendship was broken.

2. It's not difficult to borrow if you borrow and return it, and it's not difficult to borrow if you don't return it.

The two saddest words are not lovelorn, but borrowing money and not paying it back.
