Last week I ran one of the new heroics, the fancy one with the multi-faced end boss (Forge of Whatever).
The druid tank (Furyhawk-Thrall) and I rolled on Frayed Scoundrel's Cap.
He said "Oh crap, I didn't realize you needed. Here." And handed it to me.
I blinked. "Oh, no, if you need it keep it."
"No, I'm wearing T9."
I said "You're so sweet!" and thanked and /hugged him, and Magiabianca-Thrall promptly told me to back off.
They tossed /love at each other, and I grinned to myself at the cuteness of them and popped the new helm on instead of my measly old Headguard of Retaliation.
I was pretty happy after that. Not just getting a massive upgrade or them being nice but also running into another couple that pugs together.
So if you run into those two, definitely let out a "Woo!" of happy, because they're nice people.
