Dearest Tsar Doug,
No need to bring an extra change of trousers. Just make your way over to Valmontsky, and please bring all your friends . . . your valet, your ship's captain, and most especially Lillibet the Mechanic. In fact, she will be Special Guest of Honor, how's that for hospitality?
A costume also is not necessary, since we admire you most in your epaulets, plus your Admiral's cap and any other Napoleonic accessories that you chose to wear. Be advised, however, that before entering Valmontsky you will be walking through a security turnstile, and probably that hand stuffed in your shirtfront will need to removed, if however briefly.
Mere procedure, Tsar Doug, mere procedure.
At any rate, your tower suite awaiteth, and we look forward to welcoming you, Lillibet, and all your other friends/entourage at your earliest possible convenience. Until then, T.D., I remain--
The GD/GP "Big Nurse" Janet
