You are exactly right, Lyn. Heck, I still remember ice-boxes and milk delivered to our door in glass bottles/jugs (?). In fact, when I was a small child, I stumbled over a milk bottle and cut my ankle badly. I still have a huge scar, but over the last 67 years, that scar has moved from above my ankle down to almost my sole. I guess gravity is pulling everything down, huh?
