“How ring binders work. I thought you had to take out all the pages to add a new page to the back of the binder, which annoyed me in school because it could take a while having to realign all the pages to fit the holes in the binder. I was about 22 when I worked in a bookstore and my coworker saw me take all the pages out, after which she showed me how it actually works. I will never forget the look of disbelief on her face.”
