Swatter weather
Any animal (even humans), will remove themselves from your proximity after you've swat at them enough times; but not the lowly, humble, average insect. Oh no! They keep coming, and coming, no matter what you do, or how many times you do it. Rolled up newspapers that miss their mark, sharp flying hands that do the same, gaseous clouds of repellent, are not enough to daunt our minuscule friend. Not even curses work. So, as I once again swat away this "gawd only knows where it came from" fly, I am convinced once more that all insects are raving masochists.
