You ever had the feeling where you are forgetting something, you know it, however you can’t remember what? I have this feeling every now and then, and it constantly drives me deranged when I do. I can’t stop thinking and thinking, trying to remember what it is that I had forgotten, and usually I can remember whatever it was. This weekend, I had my usual list of chores that needed to be completed. I cleaned the counters, swept and mopped the floor, went through my mail, paid the bills and cooked lunch, however something still felt missing. I felt like I was forgetting something, although I couldn’t name what it was. I finished my chores about 30 minutes early, and I knew that something else was supposed to be occupying my time, although I couldn’t remember what it was. I racked my brain for a little while, however since I came up empty, I decided to kneel down and relax, and figured it would come to me. I was just start to doze off in my chair, when it hit me. The air filter! I had to change the heating and air conditioning machine’s air conditioning filter. I almost forgot to change the HEPA air filter, which would have been bad, since those filters need to be substituted fairly often. Before I forgot, I abruptly got up and changed out the air filter. I was back to being wide awake, so I decided to pass the time by playing some online games, before heading to bed.
