My socks told the story. The bottoms were more brown than white, with black specks and crumbs peppered generously all over. They were rather disgusting. So I knew it was time to steam mop. Again. I pulled out the mop and worked my way through all the tiled sections of our house, which is everything but the bedrooms. I felt a great sense of accomplishment, but then realized I was still wearing my dirty socks. Well, that wouldn’t do. I went to my room and opened my dresser to pull out another pair, and I hesitated. I had a couple pairs of brand-new socks, never worn. But did I really want to wear those? Any dirt left would certainly show up on those. Frankly, I didn’t want to know if the floors weren’t completely clean after all that effort. So I reached instead for a pair I’ve had for a while. Clean, but slightly discolored on the bottom. It would be better not to know.
