 Sergei had enemies, but none were powerful, none were motivated, and very few were even aware of being his enemy. He had sent out a written notice of enmity, but where the postal system hadn't failed, his good-for-nothing foes had, being too lazy and not curious enough to open the letters when they arrived. It made Sergei furious to think of his crisp, wrathful prose lying under days-old pizza boxes as the people he hated wallowed in deliberate slacker ignorance.
