I had an interested experience last year. After I had left a small village in the south of French, I drove on to the next town. On the way, a young man waved me. I stopped and he asks me for a lift.. As soon as he had got into the car, I said good morning to him with French and he answered in the same language. Apart from a little words, I don’t know any French at all. None of us spoke during the journey. I had nearly reached to the town, when the young man suddenly said , very slow, “ Do you speak English?” As I soon learned, he was English him!
