My Irresponsible Brother Forgot the Air Filter

My brother has never been the most responsible person in our family. Even though he’s older than me, he’s constantly forgetting things, he has no sense of time, and he’s somewhat naive. I love him dearly and he has a lot of other strong suits, but responsibility is just not one of them. When he went off to college for the first time, everyone in the family thought that he’d either die or come home within a few weeks. We never thought he’d survive on his own. Our mom had woken him up for school his entire life and she’d always been there to keep him on course. Going to college was a true sink or swim situation for him. Somehow, he managed to survive all four years and he graduated on time. A few years later, when he told us that he was purchasing his first house, we were shocked. Although he was slightly more responsible, he still wasn’t thriving. Having a house was a big responsibility, especially when there were things like HVAC systems to take care of. When I was helping him move in, I noticed the air quality was dusty and musty. I thought it was because we were stirring all the old dust up while bringing in packages. When I made a comment about changing the air filter, my brother casually mentioned that he took the old air filter out because it was dirty. However, he never said anything about putting a new one in. Turns out, he never put a new air filter in the system!
