I can relate to this sooo much. I can barely remember if I gave a book to someone to read and they probably never returned it back to me. And me being the kind hearted soul, never felt like asking them back for the book. But, I remember each of those books that once belonged to me. Let's just say, they are happier now, at other places , being in someone else's book shelf. I almost forgot about these books, thanks for reminding me about them : )
