Mr Smith lived in the country , five days a week he went to work by train every morning and came  home the same way . One morning he was reading his newspaper  on the train when a man sitting behind him , who Mr Smith had never  met  before  spoke to him . " You do not  lead  a very interesting life , do you ?  Have You ever thought of changing it ? If you  get  off the train now you will find  a new world . The world you were dreaming about all your life ! You can  fly  to different countries and make discoveries " . Mr Smith suddenly  remembered how he had flown to Canada one day . Since then he had  forbided to mention flights . It was awful . The plane was swinging  all the time , he was throwing backwards and forwards . It  stroke  him he would have  never seen his native village and his family . It was hurting to think about it . He  watched the engine was burning . And he had to land by parachute . Mr Smith was bitting his finger and turned angrily to the stranger : " I adore my life , its full of changes as it is . I will move to a new house soon . It is being  built now . Look out of the window and you will see  it " . 

Mr Smith lived in the country, five days a week he went to work by train every morning and came home the same way.
One morning he was reading his newspaper on the train when a man sitting behind him, who Mr Smith had never met before spoke to him.
" You don't lead a very interesting life, do you?
Have you ever thought of changing it? If you get off the train now you will find a new world.
The world you were dreaming about all your life! You can fly to different countries and make discoveries".
Mr Smith suddenly remembered how he had flown to Canada one day.
Since then he had forbided to mention flights.
It was awful. The plane was swinging all the time, he was throwing backwards and forwards.
It  stroke  him he would have never seen his native village and his family.
It was hurt to think about it.
He  watched the engine was burning.
And he had to land by parachute.
Mr Smith bote his finger and turned angrily to the stranger:
"I adore my life, it's full of changes as it is. I'll move to a new house soon.
It is being built now. Look out of the window and you will see it".
