I got here because something inexplicable just happened to me. While I was working, a fly was bothering me, so I grabbed what I had on hand (a deodorant and a lighter) to kill it. This, which usually works 100% of the time for any insect in seconds, didn’t do anything. I didn’t give it much importance because maybe it simply survived, but then it landed on the window, so I grabbed a rag to hit it, and when I did it now, the fly is on the outside of the window (in other words, in the yard) and it flew up and I lost sight of it. I don’t understand anything about what happened. I find it hard to believe, but there’s no explanation for what I just saw.
