You probably got some credits for doing that - and it was fun!
I had two friends who were library assistants in my junior year in high school. It was great because if I was waiting for a book that had been checked out, they’d keep their eyes peeled for it being returned and let me know so I could snap it up.
I love books. I love the smell of books. I love the feel of the pages. Nothing is better than a book!
(Unless it’s reading a book while eating a still-warm tomato from the garden.)
