i don't line anyone putting creases in my books, it bugs me. Like folding a page, etc, that would make me want to hit them over the head with the book

See I can't seem to figure out why but it only bothers me when I do it. If someone borrows a book from me and does it, it's not a big deal. My friends make fun of me all the time for the way I am...
