My sister said everywhere that she was good to her brother, but she refused to lend him 10 thousand yuan. What about this girl?

This sister is definitely not good, especially selfish. It's good for her brother to show off everywhere. Actually, most of them are not good for her brother. Showing off is actually what she lacks. As for lending money to her brother, it depends on the actual situation. If she needs money badly on the right path, but she doesn't borrow it, it is wrong for her, otherwise it is right.
