I used to play World of Warcraft as a Discipline Priest...

One day, a Blood Death Knight started attacking me because I was always in PvP mode. The thing is, they didn't have the strength to kill me because my whole thing was being a single-target healer, and I didn't have the strength to kill them because their whole thing was being unstoppable. So, we fought and fought and fought and fought and fought until we finally just bowed to each other and went our separate ways.
