My wife and I were visiting one of my sisters and her family. Partially completed, their house was made mostly of cinder blocks. I was looking down into it from behind and above. They didn’t have heat. They had a fireplace. Shifting perspective, my wife and I told them, “We have rocks that will heat your house. We’ll put them in your fireplace.” They were skeptical but we told them, “You’ll see.”
The fireplace rock seemed like a piece of broken cinderblock. It put out heat, though, lots of heat. My sister’s fireplace was back toward the house’s rear, away from the bedrooms. Because of that, most of the house wasn’t heated. They’ll all gone to bed, sleeping in one room to stay warm. For some reason, we had to keep the existence of the heating rock secret. Never understood that. But my wife and I managed to find another place to safely place it in my sister’s house, and then moved it without anyone knowing.
When my sister and her family got up, we showed/told them what we’d done. They were concerned that we wouldn’t be able to heat our own place. My wife and I laughed at that. “No, we have many fireplaces and each of them has a rock.”
I then took my sister and her family around, showing her our places. All were brick, with large yards. Sis knew of one or two, but I showed her five or six. I was letting others use these places. My wife didn’t know of some of these places, either, which made me laugh as I went about showing all the places. Some were hidden to others. I kept revealing more as we went around, opening doors to more, almost as if I was recalling them as I came across them. We then went about confirming that we did have ‘fire rocks’ in each of our places.
