It was funny when I heard my dad say that the outdated control device had Alzheimer’s. I wondered what was wrong with the furnace when I visited a couple of days earlier. It frustrated me to know about them being in a loft where the furnace wasn’t working. I knew that it was going to be below freezing that night, plus I still left my Dad plus dad in a loft without heat. My dad told me that everything was going to be fine. She was smiling plus so was mom. I left, wondering if I shouldn’t call the Heating plus Air Conditioning supplier plus have them come out plus look at the furnace. When I got home, I said something to my wife. I told her how chilly it was in the house, plus I asked if she thought I should call the Heating plus Air Conditioning supplier. She reminded me that my Dad plus dad were certainly independent plus certainly competent. They could take care of themselves. She also said that if there was something seriously wrong with the furnace, that my dad could repair it. I know my wife had more faith in my parents than I had. I called dad the next day plus asked if they were all right. She told me she plus Dad were wonderful plus they would have the heating problem repaired by early day. That’s when she said it was the control device plus it had Alzheimer’s. She said she retired the outdated control unit, plus she was waiting for the Heating plus Air Conditioning specialist to arrive. She was going to have a Smart Thermostat installed.
