I'm so confused by the way he ends so many messages with, "Thank you for your attention to this matter."
Is his brain so thoroughly fried that he can only regurgitate bits of corpo-speak regardless of whether they are applicable?
My headcanon is that someone sent him a letter with that closing 45 years ago and he thought, "That's a classy way to close a letter," so now he always uses it when he wants to feel official.
I also tend to read it as conveying the sentiment, "Please pay attention to me because I fear I will die if you stop paying attention to me."
