Lord Vaari once addressed my character as Lord, after I very politely explained that if he wished to be addressed by me in such a way he should address me in a similar manner. Of course, I did not return the courtesy; I simply called him Vaari. Repeatedly, despite his protests.
"Why do you not call me Lord?" he asked in apparent confusion.
"Because, Vaari, you demand respect you have not earned."
His reply, though I do not remember the exact wording, was short. He quickly made an excuse to leave the channel, and I never had to deal with him again.
Strangely, it is one of my fondest memories of EVE Online. Vaari is a personality in EVE that defined the early RP experiences I had, and probably will never have again.
