This happens in Australia. A driver is at a petrol station. He fills his car. He walks away to pay. A thief enters his car. He wants to steal it. The driver wants to stop the thief. He starts to run. He jumps into the window of the car.
This scares the thief. He runs away. Police are looking for the thief.
Difficult words: fill (to put petrol in), thief (a person who steals things), steal (to take things which are not yours).
