Almost! Mormons. I was already thinking how to get ride of them in a polite but definitive way when one asked me : "Vous ĂȘtes français ?"("Are you French") in a perfect French almost without any accent. And the other one continues to speak to me in French like they were Parisians. "Oh, we just have some friend who is French and teaches us..."
OK! after I got rid of them, they even spoke some words to my neighbor from Togo in his native language...
