Why yes, of course. Please ignore the make-up, would you? It's simply a formality so that those less acquainted with myself may easier identify me.
For your first lesson, as imperial royalty, you must learn to apologize immediately for any transgressions that are so much as implied upon you. For example...
*He gets down on one knee, bowing his head to the ground.*
I sincerely apologize for my earlier attempt on your life, Ser Asdf.
*He stands again.*
I also expect that you'll need to learn a bit of Ukrainian, if you want to keep up with the Imperator, hm?
When you answer a question, be firm and assured of your answer. The Imperator might not wear it on his sleeve, but you'd be surprised to learn how much he absolutely despises indecision.
I'll ignore the informality in your language at the moment, but let's keep in mind a tone that evokes intellect and nobility. For example - I shall, not I should.
*He smiles slightly.*
It's really annoying to have to talk so fancy, huh?
Either way, onto the language, then.
First, let's start from square one - introducing yourself. To say, "Hello, my name is Joshua Weller," I'd say "Dobroho dnya, mene zvaty Joshua."
...Joshua doesn't translate so well, I'm afraid, though in Ukrainian I would be called "Dzhoshua."
