We have some copies of royal correspondence found in Egypt, written on cuneiform tablets. They used them for messages to foreign kings because they're compact and durable. A lot of the surviving tablets are begging letters asking the Egyptians for gold. We even have some practice tablets from teaching Egyptian scribes to do this.
Anyway I think some of these documents are of communications with Hittite kings, so it would be great to get some instances of the "other side" of some of these letters.

I'm imagining a class on "begging for gold" being given to young Egyptian scribes.
That would be Amarna Letters 41-44.
A quotation from a letter sent by Ankhesenamun, Tutankhamun's widow, to Hittite king Šuppiluliuma I was found in Ḫattuša. Ankhesenamun asked Šuppiluliuma to send her one of her sons to marry her and become king of Egypt. Šuppiluliuma initially thinks this is a ruse, but the story eventually checks out and Šuppiluliuma sends a son. That son is killed on his journey and a war between Egypt and Ḫattuša ensues.
