The cat sat on the mat is not a story; the cat sat on the dog’s mat is the beginning of an exciting story, and out of that collision, perhaps, there comes a sense of retribution. Now you may call that God, or you may call it the presence of fatalistic forces in society, or you may call it man’s inhumanity to man. But, in the immortal words of P.G. Wodehouse, what it boils down to is that if your character does something wrong, sooner or later if he walks down a dark street, fate will slip out with a stuffed eel-skin and get him.
