One day an old lady wants to go to London to see her daughter. She gets up early and gets to the small station at 9 o'clock in the morning. Because this is her first travel to London, she doesn't know the train time. She is worried. At that moment, she sees a little boy running to her. She stops him and asks him what time the train will get to the station and when the train will leave for London. The boy looks at the woman and says “tu: tu: tu: tu: tu: just like firing a gun. Then he runs away. The old lady is very surprised and gets angry. She sits on a chair and thinks about the boy's words. Then she begins to smile. She can't help crying out, "What a clever boy! He tells me the time in such a way." Do you know the time?
