Do you speak English?

I had an amusing experience last year.After I had left a small village in the south of France, l drove on to the next town.On the way, a young man waved to me.I stopped and he asked me for a lift.As soon as he had got into the car,I said good morning to him in French and he replied in the same language.Apart from a few words,I do not know any French at all.Neither of us spoke during the journey.I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?'As I soon learnt, he was English himself!
