A childhood belief about technology

When I was a kid, I had two computers in my home, an Amiga 500 which uses the common 3 ½ inch floppy disks and a Commodore Colt that takes the older 5 ¼ inch floppy disks. Neither of my two computers back then had hard disk drives so I jumped to the conclusion that the 3 ½ inch disks of the Amiga were all hard disks because they had a much harder surface and were less flexible than the 5 ¼ inch disks. I had over one hundred games for the Amiga and I told some of the teachers at my school that I had a computer with over one hundred hard disks and they were wondering how the heck my family could afford so many hard disks and how I could fit all of the hard disks into my computer. I believed that all 3 ½ inch floppy disks were hard disks until I was 14, when my Info Tech teach set me straight by getting my to write one hundred lines stating that 3 ½ inch disks are floppy disks.
