One day John was doing some shopping in the market when he noticed a beautiful young woman there.She was very well-dressed and he watched her as she walked around, looking at the fruit and vegetables which were for sale.The market was very crowded, but this woman was so beautiful that she stood out in the crowd."She looks like a film star," thought John to himself.Suddenly a thief ran through the crowd and seized the woman's bag and ran away.She screamed.John ran as quickly as he could to the nearest phone box.He dialed 999."Please come to the market square at once,"he asked the police,"A thief has nun off with a lady's bag." John then returned to the market and tried to calm the young woman.However, the thief had already returned and was talking to the young woman.They explained to John that they were only making a film.
