How do you guys feel about people borrowing your books? At first I didn't mind it. But my best friend proved to me that she can't be trusted around my books and her books period. She spit water all over two of my books and her own book she had the pages bent and ripped. Now I have trusts issues with people borrowing my books. (Especially because books are VERY expensive. I have over 1000 dollars worth of books on my shelf.)
