Passive Aggression

If you take someone's possessions or money, they can always get more. But to really hurt them, take up their irreplaceable time. Such an attack imposes permanent injury from which they can never recover.

Drive slow on the highway. Make customers wait in long lines; after all, their time doesn't matter to you, and you can subject them to impulse purchase advertising. Why punch your enemy in the face when you can bury him in tedious paperwork? Don't kill his pets and set his house on fire, but buy him a television and free Netflix subscription. Take him to sporting events and force him to play video games. Drown him in drink and drugs. Ruthlessly incapacitate by stealing time and forcing him into a spectator's existence.

Block your enemy from enjoying what is good in life. Frustrate every attempt at a goal and impose arbitrary obstacles so they give up. Encourage quitting and offer surrogates and simulation to draw them away from reality.

But most of all, waste their time and take joy in knowing you have stolen potential from them and imposed hardships that will last forever.
