I spent the morning smashing fliesI killed one fly against the doorjamb. Another I stalked into the kitchen...A third fly wavered by the kitchen window. When I swatted, a wild ferocious swing, a whole trembling crowd shot from the window like pebbles from a blunderbuss, then settled back. My heart pounded. I felt flushed with disgust and irritation. Why must I always have such obstacles to my writing?
