I like lists of 10, and have suggested others, but here are the TEN things that I love about France - in no particular order;
1) The profiliferation of books and resoect for authors. I read French far better than I speak it.
2) Puces and Brocantes; Great ways to discover new places and see the French bargaining, something I am not very good at!
3) Outdoor cafés watching the world go by, a great lesson in relaxation - who needs Yoga?
4) Specialist regional food shops - cheese, wines and things I have never seen before.
5) The amazing TGV , which alas doesn't cover our new area.
6) War Graves in Northern France. Moving and amazing that they are so well respected and looked after by the French in spite of the often offensive comments made about them by some Americans, and others. ('cheese-eating surrender-monkeys' being one such example)
7) 2CV's and Citroen Traction automobiles. Still to be seen and still VERY, VERY French.
8) Vulgar and non PC place and food names. I had a friend who once made a meal and menu of such items - and delicious it was too (food and wine only of course). One of my favorite named villages is called 'Donkey's Fart' and I can imagine the hilarity of translating it to friends who get letters! Bit basic aren't I?
9) Ancient doors everywhere.
10) The ability of every Frenchman (seemingly) to do everything from building a house to running a farm even if his 'real' job is something like a Cost Accountant. As one of Nature's practical incompetents this always leaves me stunned.
