There was another that happened a long while ago. Not really embarassing, but..
Me and a Friend had found a pretty much empty Port Royal and decided to stay on that Port Royal for an invasion. Then i found someone, cant remember the name but the person had 'dog' in the name. So it was just me, my friend and 'dog' in the crew. I look up at the crew and find out he's knocked out. So i hurry over to where he was, but it was to late. So i typed in "Sorry about that, doggy" in which the reply was: "Do you always talk low to your friends?" or something like that.
After that, i had thought up of some new nicknames for the person. But i thought back at that moment, i cant really be to hard on him. Your reading the text, so he might have looked at my comment as kinda rude while i meant it in a more cheerfull tone. "Sorry about that doggy, i was heading over to revive you but you disappeared before i could get there. I sorry" Is what i should have typed..
EDIT: Hey, could have been worse. could have been someone walking up to you and shouting out "Hey! Your that person that was really rude to the GM's/Constance! Your the reason she's crying! Your guild should boot you out!" when i was just doing the roleplaying stuff at GM Stuff or Ghost stuff in which i was saying the usual. "Long live Jolly Roger, Scourge of the Caribbean!" I wasn't being rude to the GM/Ghost by saying that now, was i? Or is having Jolly Roger as one of your favorite characters against the rules now?
