I'd like to think that I'm pretty polite most of the time, but I'll admit that I have no idea what's expected of me in extremely formal situations. I mean, it was only a few weeks ago that I learned that there's actually a huge (and sometimes insulting) difference between addressing someone as "your highness" and "your majesty," so in the unlikely event that I ever actually meet a king or queen, I'm going to be at a loss.
I do, however, know one thing about meeting royalty: You don't spit on them. Especially if the royalty in question is a barbarian king from the fifth century. Especially if it's Aric of Dacia, a barbarian king from the fifth century who is also wearing a suit of high-tech armor that recently allowed him to defeat an entire alien army pretty much singlehandedly. That's... that's not going to work out well, and it's a hot tip that you could probably share with the cast of X-O Manowar #40, by Robert Venditti and Rafa Sandoval. Check out a preview!
