Read the text:
Mr and Mrs Brown had two daughters and two sons. Both the
daughters married, and then both the sons married too. Soon
Mr and Mrs Brown had a granddaughter, and then they had
two grandsons. They were very happy.
Then one of their daughters had another baby, and she telephoned
her mother, "Please come and help with your new
granddaughter." Mrs Brown went quickly, but Mr Brown
stayed at home, because he was nearer his job there. But he
said, "I'll come on Friday evening, and I'll stay till Monday
morning."
On Friday evening, after work, Mr Brown got into a train.
He was very happy. "I'm going to see my new granddaughter

There were three empty places in the train. There was an old
man beside one empty place, and Mr Brown went to him and

woman beside that. Mr Brown said to her, "Are you a
grandmother?"
The woman answered, "Yes, I have two granddaughters and
two grandsons."

beside that, and Mr Brown said to him, "And are you a
