Every once in a while human beings actually impressed me with their honor ability. I can tell you that it isn’t very often. For the most part, I feel like I am disappointed by other humans more often than not. It’s those special characters who come into your life here and there that make you re-examine your own pessimistic outlook on the species. For me, one of those magical unicorns has been my ex-father-in-law. To be fair, we didn’t get along very well while I was married to my ex. However, since we broke up a few months ago my father-in-law has been an amazing friend and advocate for me. Besides, he has been a major player in my central heating, cooling, and air quality control system. You see, my father-in-law has been a professional heating, cooling, and ventilation technician for most of his life. He has been in the indoor air quality control industry for longer than I’ve been alive. When my ex and I were together my father-in-law would often give us free air filter changes and diagnostic services for our central heating and cooling units. I definitely appreciated his heating and cooling equipment oversight at the time. But since I’ve been alone, I’ve enjoyed his HVAC maintenance efforts even more. You see, every few months my father-in-law checks in to make sure that my indoor air quality is up to par. He gives me free equipment inspections and repair services. Without him I don’t know how this hot-and-cold story would have turned out.
