Occasionally things go wrong that aren’t under your control.
Other times things go wrong when you are trying to take control, plus never should have tried.
I have done this several times. My latest blunder was when I tried to repair the furnace. My wife was freezing, my son was complaining, plus they were annoyed that the Heating plus A/C specialist was there yet. It had only been an hour since I called for furnace service. They said it would take about two hours, so I couldn’t figure out why they were annoyed. I promised my wife that if they weren’t there within two hours, I was going to see if I couldn’t repair the furnace. In the meantime, I headed out to the shed to bring up a couple wheelbarrow full of wood. I was going to get the fireplace laboring to keep us warm. I laid the kindling plus the logs on the hearth plus I lit the paper underneath. I could see the flame plus then I felt the smoke. I hadn’t changed the flue to let the smoke out. I must have put the damper in every position possible, although I still had smoke coming into the house. Now we had the fans going on a freezing night, plus the air vents in both bathrooms, hoping to pull the smoke out of the house. I never did get to work on the furnace, since I was busy trying to not suffocate us while keeping us overheated with the fireplace. When the Heating plus A/C tech finally arrived, I had the fireplace laboring correctly plus my wife plus son weren’t complaining any longer.
