We really have lost the art of writing appropriately to our superiors. ‘Dear’, ‘Hey’, ‘Hi’ doesn’t really cut it. So how about we return to something like:
Say to the king, my lord, my god, my Sun: Message of Adda-danur your servant, the dirt at your feet. I fall at the feet of the king, my lord, my god, my Sun, 7 times and 7 times. I looked this way, and I looked that way, and there was no light. Then I looked towards the king, my lord, and there was light. A brick may move from under its partner, still I will not move from under the feet of the king, my lord.
Written to Amen-hetep III, who happened to be a pharaoh in the second millennium. But spare a thought for the poor scribe, pushing this stuff into a piece of wet clay before getting to the substance of the message.
