French attitude toward infidelity, and gossip
Being a puritanical American with a bourgeois attitude toward sex (/S), I don't see why Juliette's kiss in the street with Noah so scandalous. I thought the French had a more pragmatic attitude toward infidelity. She is married to an old man who has been absent from the scene for years. Maybe kissing him on the street violates the code of keeping it discreet?
Or is there a double standard in France as well? (Men may have mistresses, but women can't?)
And Sabine complained that Juliette's affair was a topic of gossip all over the university, but was it?
