From the Fire Nation, With Love
Read carefully, you shit-brained eunuch ingrate—ahem—DearBELOVED SON,
I am terribly unhappy to be informed that you still have not managed to find your wife and bring her back with you. You ARE a prince. Surely getting a woman to agree to marry you and rule the most powerful nation in the world—no thanks to you, btw—is not that hard. Your sister could have gotten herself a wife by now, and she's not even a man. Must you fail in every task I set before you? Here I offer you a chance to go home without the Avatar and you bungle this mission as well. My good patience is growing thin. All the Northern Tribes, not just hers, are threatening to resume hostilities en masse if I don't produce proof that you intend to marry this girl. This girl that YOU got yourself engaged to, need I remind you. Honestly, I thought your uncle would have taught you not to give jewelry to girls just because you want to get into their skirts; it gives them the wrong impression.
Get your act together,
Daddy
