Lesson25 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 understood.
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 do not understand them!
Do they speak English?
