Being a hero was much easier than being a coward. To be a hero, you only had to be brave for a moment - when you took out the gun, threw the bomb, pressed the detonator, did away with the tyrant, and away with yourself as well. But to be a coward was to embark on a career that lasted a lifetime. You couldn't ever relax. You had to anticipate the next occasion when you would have to make excuses for yourself, dither, cringe, reacquaint yourself with the taste of rubber boots and the state of your own fallen, abject character. Being a coward required pertinacity, persistence, a refusal to change - which made it, in a way, a kind of courage.
