I don’t generally reread books. At least not in their entirety. When it comes to me re-reading something, it consists of me pulling the book from the shelf and reading my favorite sections(s) then quickly returning it to its designated spot. I don’t often sit down and take a book I’ve already completed for a second or third spin.
I’m not sure when I got to a point where I stopped re-reading things but I don’t remember a time where I was ever really interested in doing it in the first place. If I wanted to deep dive into the psychology of it, I could probably explain it away. Keep on reading!
