Occasionally, a house-fly gets, inside. And on those occasions, I can usually swat the intruder using a diversionary technique. When the intended prey lights, I hold the deadly swatter in my right hand and stick my left out to the side (or up, depending). Then, I wiggle the fingers of the left hand like the legs (in my imagination, anyway) of a web-challenged spider.
See, I know that flies have much faster reaction time than I do. But, they don't divide their attention very well. My technique forces them to try and while they are trying, the deadly right hand acts.
Usually. This morning, Mew was staring intently at a dining chair's back. When I asked her what she was doing, she glanced quickly at me and then resumed her stare. Moving closer, I could see a fly that had been elusive since yesterday. Grabbing the swatter from its hook, I went into my act. Between my twitching fingers and Mew's twitching whiskers, it was truly distracted.
It took two of us to hunt this one down. Cooperation between the species . . .
