So the evening after I was harassed by server bullies and husband and I lamented being stuck on a PVP server for the 100th time, I walked past him and he said, "I just had my first moment where I'm glad we're on a PVP server."
And I said "Wha?"
He was mining in old-world Azeroth on his 80 death knight, riding toward a thorium node, when he sees a level 56 night elf get to the node before him*. He stops at the node, surprised when the night elf raises his mining pick anyway. Husband one-shots him.
When you see a high level running toward you and don't run, you're kind of asking for it.
Later, he saw a level 73 paladin in Northrend going for the same saronite node. But this player stopped, turned, and left the node alone.
* This information is wrong and has been corrected in the comments. Husband got to the node, started mining, and the lowbie came up and started trying to mine after husband had started.
