I actually thought this when I was a kid...

I was probably about 6, or however old you are when you're in first grade. My mom took me school supply shopping at a new Jewel in a new neighborhood. I remember my mom telling me that one of our old neighbors built the Jewel. I picked up a notebook that had a few different colored chains of concentric spheres flying around the cover.

I thought that the notebook must have been used before, and that my old neighbor, the one who helped build the Jewel, created a machine with multiple erasers on it and used it to erase all of the pages in all of the used notebooks that Jewel sold.
