My maternal grandma was equally as nosey as yours but she would never admit to it, lollolI remember my grandmother running for the phone when someone else ring would buzz that she wanted to hear what they were talking about. LOL . Her ring was 2 longs and a short but , she was nosey and wanted to hear what the neighbors were talking about. Like you said to call out you had to ring the operator and she would place the call. They had a 12 volt wind mill generator that charged a couple of batteries and it would power a couple lights and the radio. Always listened to Paul Harvey every day at lunch. When I was about 6 or 7 they got electricity. They had a flushing stool before they got power!
I remember her coal furnace that had a giant register with a seat on it, in her living room. The seat could get pretty warm but none of us grandkids ever got burned from sitting on it. That was the prime place sit in the winter. Grandma kept seat position on a “first come first served” basis along with “move your feet, lose your seat”, lollol
I was probably the only family member sad to see the coal furnace replaced by fuel oil because the seat went down the road with the coal furnace.
