so after 1 or 2 years of French class, I participated in a student exchange project for 2 months, meaning my French exchange partner lived with my family for 2 months, and then I lived with his for 2.
In France, he went to a boarding school, so we stayed at school during the week and got back to his family during the weekend. After the first week of school, we went back to his parents' house and his mother asked me "what did you like most about French school?"
A little ashamed, yet proudly I answered, that the best thing is how comfortable social situations are, how close people get casually, especially, how when greeting girls you do "accolades" (those kisses where your cheeks touch/get close and you kiss the air). So I answered something like "J'aime comme pour faire la salutation, on baise les filles"
His mother looked at me in shock, everyone in the room gasped! She told the kids (July, 11yo & Clara, 12yo) to quickly go upstairs, and gave me an angry look.
