I remember this time when I was young when my parents were fighting.
I learned that my father tried to fix the HVAC system on his own.
My mother was yelling at him because she told him to hire the professional HVAC company to take care of everything. Evidently, the warranty on the HVAC system was now void because he tried to work on it himself and he ended up completely damaging the HVAC system so it would no longer work. They were going to have to pay a large amount of money to have it fixed because there was no longer a valid warranty. Even when the HVAC worker came to work on the thing, he suggested that they get a new HVAC system because the damage to the HVAC was very extensive. He said he could repair it but it was going to cost a small fortune and they would be better off getting a new HVAC system altogether. This was a hard lesson for my father and he ended up going for the new HVAC system. The new HVAC system was at least more energy efficient and he tried to throw that argument out there to my mother, but the argument was pretty weak. Even I told my mother not to be so hard on my dad because I said that nobody is perfect. My parents both appreciated that coming from me, and I think it helped to calm them down. I just hoped that after that experience, I didn’t get in trouble over things that seemed to be petty in comparison.
