>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.
Why?
I mean this sincerely. Why is the message you quoted not enough?
I hear you. I get it enough to know it’s needed, but actually doing it can be hard. LLMs can be nice for that.
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.
Manners. It's just rude if I'm not somewhat close to the person.
