Writing a letter to Prince Sebastien of Luxembourg
I am a big fan of his, and I think he's really cute.
I have his adress (royal family of Luxembourg's adress), I want to write to him, but I don't know what about!? I know silly, but I want to get to know him more. So by writing this letter I hope to "get to know him" more, even though I know he probably won't reply himself ¬_¬ it's still worth a try...
Anyway, what is the proper way to adress him, and what should I write in the letter?
