I was on my Blood Elf Rogue in Durotar, doing this quest. I had just killed Lieutenant Palliter when this happened:

OK, so clearly this guy is not happy that I got to Palliter before he did. But I don’t know what he meant when he said ‘I WILL RESPAWN’.
I leave him to his ranting and head outside to turn in the quest. But I realise something. Nuadrise is getting on at me for being ‘not nice’, yet he said ‘fuck you’ to me over something so trivial. That makes him a hypocrite, so I tell him.

And that’s that. I took these screenshots, sent them to Geo and continued my adventures as a Rogue, all the while hoping that Nuadrise was feeling quite stupid.
