I was standing in my kitchen, making coffee with my Aeropress, when I heard a noise. The noise sounded like something plastic bounced off something metal and then landed on the floor. I looked around the kitchen floor, I have a very small kitchen, and was unable to find any random bits of plastic that didn't belong. On a whim, I decided to look behind the stove as well, since there is a very sizable gap between the stove and the wall. Sitting in the gap was a bottle of Purell hand sanitizer, but nothing else was readily apparent. Forgetting about the sound, since I could find nothing amiss, I went back to making my coffee.
