I would sneak into these asshole's houses and live in their attic during the day. At night, I would lock their doors and drug them in their sleep. They wouldn't be sleepy; they would simply feel paralyzed. I would make small lacerations in their skin every night while they watched me do it. Once their fear became overwhelming, they would eventually fall asleep. At this time, I would crawl back into their attic to await the next night. They would wonder if I was really there, but, then they would look at their mangled arms and retreat into their mind for comfort.
I hate people who feel that it is their job to make someone else's already meaningless life any harder.
