Our guild is run by a couple. We were trying to get a raiding group setup by recruiting just a raid-leader, then comprise the raid of our guild members. All was fine until the guy of the couple wanted to recruit raiders to fill some of the raid. That didn't go down to well with the girl of the couple, and then the guy was "talking" to me about it in vent for about 30 before I had to log out due to me having a bad headache from it all.
No tears there, but he tends to annoy me a lot in vent, so I usually rage quit.
TBH, I don't think I've ever seen a RL or a GM make someone cry...
