I got one at my house. And I’m betting you have one too!
Mine is a 1 X 2’ patch on the hardwood floor of what is now my office/ sewing room, with the finish worn off. This room was for my bedridden mother in law when we bought our house, and this spot is the spot where everyone went to stand or sit beside her bed. I stood there a gazillion times over six years. The hospital equipments is all gone and the rooms been painted and refurnished. But there is still that one spot.
Initially I wanted it fixed, but we had bigger things that needed attention. And now, well, I’ve grown a little attached to it.
