1. Stickers on the cover: They are not easy to remove and they will leave a sticky residue and I will get upset.
2. Movie covers on books: I really just don’t see a point in making the book have a completely different cover. I like all my book series to match and movie covers just don’t.
3. Not all books being the same size: I like to have my bookshelves looking perfect. When books come in different sizes, it really bothers me.
