How to Talk to Someone Politely

Like you're trying not to overtly mention your interlocutor, but keep it like an understood thing. It's something that like a lot of conlangers might not get into because it's a discourse thing. But it's a really interesting thing that it almost doesn't necessarily matter what you're grabbing grammatically.
