What if your friend asks you to borrow clothes and doesn't want to borrow them?

I used to have a backpack of my own. I liked the style very much, and my friend took a fancy to it, so I had to borrow it for my own use. Later, she even told me that the bag was scratched by a thief on the bus, so she threw it away directly, which made me angry. This friend is also a person who likes to borrow clothes from others. If she likes any of your clothes, she will ask you to borrow them. Of course, I have never borrowed clothes.
