This annoying fly just would not stop so I had to kill it. It was very elusive and I missed many times. It flew so fast, and sometimes it would stop somewhere and I would approach it, but only to miss. Its reflexes were just incredible. Hours later I saw it on my bathtub, and it did not appear to notice my presence. I could see it crawling slowly. I approached it quickly and squashed it, finally feeling relieved and even celebrating. Then when I looked at it, I realized it was just a harmless potato bug that did nothing wrong. I feel soooo bad. I can't get my mind off of it now.
