    A group of friends from Italy wanted to do something different for their vacation. They decided to drive through Australia in a jeep. The journey was a real adventure, but sometimes the long hours on the road made them tired.

    It was Bill's turn to drive. Tony, Allan and Jeff were sleeping. Bill was thinking of the cool drink and shower in the next town when suddenly something jumped in front of the jeep. Bill tried to stop the jeep, but it was too late, he hit it. When the four friends got out, they saw a kangaroo lying on the road. They thought it was dead. What could they do? It wasn't their fault. It was an accident.

    The friends were sad, but they wanted to have a photo of the kangaroo to show everyone back home. Jeff got his camera, and the others picked up the kangaroo and stood it up against the jeep.__ They put a cap, sunglasses and a jacket on him. They took several photos with the kangaroo.

Suddenly, to their surprise, the kangaroo moved its head—moved its body, and jumped away with Bill's cap, Allan's sunglasses, and Tony's jacket—-with his passport and one thousand dollars.
