An old woman wants to go to New York to see her son. She gets up early and gets to the station at nine o'clock in the morning. When does the train come and leave? She is very worried. She stops a boy and asks him. The boy looks at the woman and says “two to two”. The old woman sits in the chair and thinks and thinks.

— Two kilos, please.

— I         lots of animals.

— My father went to the Great Wall.

— They went there at 8:00.
