The whole article is about AI being bullied into actually being direct
But it's handy when the recipient is less familiar. When I'm writing to my kid's school's principal about some issue, I can't really say, "Susan's lunch money got stolen. Please address it." There has to be more. And it can be hard knowing what that needs to be, especially for a non-native speaker. LLMs tend to take it too far in the other direction, but you can get it to tone it down, or just take the pieces that you like.
Why?
I mean this sincerely. Why is the message you quoted not enough?
I don't always _feel_ autistic, but stuff like this reminds me that I'm not normal.
Being too flowery and indirect is annoying but not impolite. If you overdo it then people may still get annoyed with you, but for different reasons. For most situations you don’t need too much, a salutation and a “I hope you’re doing well” and a brief mention of who you are and what you’re writing about can suffice.
