You entirely need to be careful about who you choose to hang out with.
l acquired this at an early age after watching my sister fall into the wrong crowd and make a huge amount of bad mistakes.
She was constantly guilty by association for the sins of her peers. Beyond that, it seemed as though these closely-knit drawback influences had a horrible effect on one another. As an adult I have constantly been careful to steer clear of rough crowds. I do not want to fall into any of their shenanigans. Evidently, I also need to be careful about falling into the company of bad heating and cooling device owners. Several years ago I started hanging out with a group of people who constantly talk about indoor air quality control. However, they never mentioned maintaining their heating and cooling devices. They only discuss the merits of having a high powered Heating and A/C device so they can change the temperature control unit settings whenever they want to. You might say that they are high maintenance when it comes to indoor air temperature but not indoor air quality. Because I was at a rather impressionable age and had no clue how heating and cooling devices work, I followed their lead. I was constantly adjusting my temperature control unit settings but never upset about the routine repair appointments, air filter fluctuations, or ductwork cleaning. This Heating and A/C irresponsibility came back to bite me in the butt while I was making a wedding cake for one of my friends. Just as I finished icing the appealing cake my a/c device kicked into gear. Suddenly, dirt and dander came flying through my HVAC vents and coated the cake with filth. That morning I realized that Heating and A/C device work matters more than temperature control.
