Knocking flies out of the air: It started some days ago when walking my dogs. A fly was buzzing around me and so I thrust out my hand in its general direction. Whack! I caught it on my thumb somehow and sent it on a stunned beeline to the ground. Where it remained for some seconds before dizzily flying away--away from me. But then, you know, something similar happened today as an insect--perhaps a firefly--got too close to me and I smacked it with one of my fingernails, accidentally as I remember it (didn't even know he was there). The beast went shooting down... down... but recovered before it struck the ground. And I have some recollection of doing something like that again later today, too, but details escape. The real achievement was the fly whack. Those things are quick.
