What are some things that make you sick when it comes to reading and literature?

I can feel sick when a favorite character dies. As you’re reading along, you get so invested in the characters within the book/series (especially your favorite ones). It’s always sad to see that person go and realize you won’t get to read about them anymore.

Have you ever read a book and then realized you didn’t like it when by the time you go to the end? I’ve had that happen to me once. I was reading a book and it was a decent enough book until I got to the end. The ending was what killed the book for me. I hated that book when I finished it because of the ending. I’ll never read anything from that particular author ever again because I don’t want to waste my time on a book with a terrible ending.
