You must have been very generous and sharing of your things in the past. That’s why they assume you will let them borrow your stuff?

I bought I purse while with a friend, an expensive evening bag. She made a comment that she was going to borrow it. I didn’t say a word. Had she asked, I’d have said ‘no’. The nerve of her, IMHO. We’re not really friends any more. She was really rude and nervy with other things, too.
