I, leaning close to a pair of flies with a raised fist: "found you, you stupid little... well not that stupid..."
brings down fist, one is crushed and the other dodges by close to my body, outpacing how fast my vision can maintain focus.
I, inspecting fist: "but a little."
I search walls for a minute.
I grab some heavy, but soft plastic packaging and slap what is soon after revealed to be a corpse.
I search for another minute, finding the fly that might be the last one.
It does not get a chance to react.
also I: "I'm not a villain."
