25,Do the English speak English

I arrived in London at last. The railway station was big,black and dark. I did not know the way to my hotel,so I asked a porter. I not only spoke English very carefully,but very clearly as well. The porter, however, could not understand me. I repeated my question several times and at last he understand . He answered me, but he spoke neither slowly nor clearly. "I am a foreigner,' I said. Then he spoke slowly, but I could not understand him. My teacher never spoke English like that! the porter and I looked at each other and smiled. Then he said something and I understood it. ' You'll soon learn English!' he said. I wonder. In England, each person speaks a different language. The English understand each other, but I don't understand them! Do they speak English?
