Years ago when I was a very socially inadequate 8th-grader, I was too shy to check out books from the school library, so I just stuffed the ones I wanted in my backpack and returned them to the shelves when I was finished. I returned all the books I read except The Half-Blood Prince, which I forgot to return for some reason. I graduated HS back in June and the book is still in my possession. It's a hardcover too, although it's missing the dust sleeve. I'd return it but it holds a sort of sentimental value to me now.
I'm interested to hear other stories from the fellow book thieves of reddit!
