Indoor mixing in private homes has been always legal in France
It has, limited to 6 people and a recommendation to stay within a bubble. But the messages have got lost over the last few months.
TBH, I don't really know anyone who's been breaking that 6-person rule in France, but I am very aware that lots of people probably are.
I agree that most people are not social distancing here; only a tiny minority are using hand gel at the entrance to shops or, in my local supermarket, taking one of the anti-theft tabs you're meant to pick up as you go in so that they can adhere to the maximum capacity. And the ski season, where lifts were shut so the lower slopes were mobbed (so I was told, I did not witness this as I didn't go anywhere near a ski resort) was clearly meant to try and help some hotels and the cafés and bars doing takeaway to survive, but there was a big spike afterwards.
I know so many people here who are wary of the vaccine, it's going to be hard to roll it out. People living in the UK really can't imagine how deeply entrenched a wariness towards central authorities and mass campaigns like that is here. The history of a country affects it for a very, very long time.
DS1's lycée has been doing 1 week in school/1 week at home for months now, in half groups.
