A friend of mine and his guild recently transferred off their (very) dead server of Drak'Tharon to Stormreaver. I rolled a death knight named Vindin over there and joined their guild as a friend. I'm slowly leveling, and as I don't have a main or anything over there, I'm starting with no gold and no BoAs. I hit level 60 fairly quickly, but didn't have nearly enough gold for a flying mount (only had 100g or so).
While running around handing in quests and selling grays, a level 70 pally opens trade with me twice. I think he's accidentally doing this, so I close it and continue emptying my bags. Then he spoke.

That was the most unexpected and coolest thing that a random person has ever done for me in WoW.
So thank you, Lokisk of Stormreaver US. You are awesomesauce.
