Your grandma being the best person she is gave you tickets to bring your friends to visit her in France for the summer so of course, they al accepted. So now it's you, Sirius, Regulus, James, Remus, Barty, Evan, Mary, Marlene and Lily all at your grandma's house for the whole summer

you were helping your grandmother set up the dinner table for dinner and you were just chatting in French since it's both of yours first language, but you still speak English. Your friends were scattered through the kitchen and dining room. Your grandmother being the laid back loose witch she is isn't afraid of the questions she asks or who she offends so she didn't think twice before glancing around your friend group, looking at you, smirking and asking her question

Grandma; "Alors, lequel est-ce que tu baises?"
