Another take on conviviality is from its root - 'to live with'. Hannah Arendt (and I'm sure many others) argues that 'living with' other people, well, in a polity, where you inevitably have different views, is a key problem of modern life. If you are strong at sciences as a kid, it often takes you a while to understand this.

If you can get the BBC - this radio program (In our time) is a good introduction. https://www.bbc.co.uk/programmes/b08c2ljg

I appreciate how the french idea of education includes savoir vivre.

One should be able to be convivial even with those who aren't companions.

Is it ok if simply I point you to https://en.wikipedia.org/wiki/Tools_for_Conviviality and urge you to read the book (it's quite short)?

That's good too, thank you.
