Do you have any? I do.
- I'm not one that insists on having all of my books in alphabetical order but once read a series must remain together.
- I must have separate shelves for my TBR books and those books that I've already read. If I have more than 1 book in a particular series in my TBR do they need to stay together? No. I know, weird.
- I crack spines *ducks and runs* but insist on not having the page turned down to hold a page. That's what a bookmark is for people!
Those are just a few off the top of my head. What are some of your little quirks?
