I’m sure that most people have things they have done in their past that haunt them.
In my case I have made numerous mistakes.
I can remember when I bought a really nice first car that was kind of a luxury vehicle. I thought the vehicle would run perfectly forever out of my youthful ignorance. My father reminded me that I had to change the oil, but I always put it off until the engine eventually locked up. It seemed to happen so fast and I felt so stupid for allowing that to happen. So I totally killed the engine and I ended up just junking my vehicle. It was a sad moment for me as I remembered all the things I loved about that car. The climate control system was amazing. The heating system kept me warm in the winter and the A/C system was working well in the summer months. It’s just that I didn’t take good care of my car, but I did take care of my next car which was a Jeep. I actually changed my own oil. Eventually when I started living on my own, I didn’t take care of the HVAC system. I thought that was the responsibility of the landlord, but it turned out that I was supposed to be changing the air filters. I never bothered to do that and then the HVAC had a major system failure. I ended up having to pay for the damages which taught me another valuable lesson. Now that I own my own place, I take good care of everything. I especially make sure to keep up with all my HVAC system maintenance.
