I can still think back to this time when I was young when our parents were fighting.
I learned that my dad did his best to fix the Heating, Ventilation & A/C system on his own, however my mother was yelling at him because he told him to hire the professional Heating, Ventilation & A/C supplier to take care of all of the little things.
To keep a long story short, the warranty on the Heating, Ventilation & A/C system was now void because he tried to work on it himself and he ended up completely damaging the Heating, Ventilation & A/C system so it would no longer work, but they were going to have to spend money a crucial amount of currency to have it fixed thanks to the fact that there was no longer a valid warranty. Even when the Heating, Ventilation & A/C worker came to work on the thing, he advised that they get a brand new version of Heating, Ventilation & A/C system because the damage to the Heating, Ventilation & A/C was easily extensive; He said he could service it but it was going to cost a huge amount of money and they would be better off getting a modern Heating, Ventilation & A/C system altogether. This was a strenuous lesson for our father and he ended up going for the modern Heating, Ventilation & A/C system. The modern Heating, Ventilation & A/C system was at least more energy efficient and he used his best efforts to throw that argument out there to our mother, but the argument was extremely weak. Even I told our mother not to be so tough on our Mom because I said that nobody is perfect. My parents both loved that coming from me, plus I suppose it helped to get them to relax. I just hoped that after that experience, I didn’t get in trouble over these things that seemed to be petty in comparison.
