Okay so Chris is on quidditch with Sy, so Rosy is family by default because that's just how it works for coppertail quidditch obvs. They take that shit seriously. Which means Rosy gets the benefits of a slightly less grumpy Chris.

But per your bullet points, I actually really do want Chris to attempt to teach her how to meditate - it could be like a collaboration of two forces that want to figure out what the fuck meditation is all about anyway, because it'll just be a really grumpy old man attempting to teach a competitive mom how to meditate and it'd be hilarious. Because they give up an hour into it and decide to go do something that actually takes energy.

But anyway, so basically, Chris respects Rosy because she's family is what I have to offer you lol
