If someone destroyed a book you loaned them, would you be furious?

I know just how you feel. I used to loan books to my brother (who was already married and moved out ) and he would ruin them. The thing was, Mom told him he could have them, and when I told her not to loan them to him he ruined them, she told me I HAD to let him read them. So I made her buy my new ones every time he trashed one. She finally quit offering them to him. And my best friend now 'borrowed' a book in like September and never gave it back. I saw it at her house all screwed up. I didn't fight with her about it, I am old and can afford to replace it myself, but the next time she asked, I just gave her authors names and offered to go to the bookstore with her to pick one out, but ignored her hint to get one of mine for her. When you love books like we do, it is a big deal when someone trashes one. Could you tell him you want to reread it and ask for a replacement?
