Life is wholly unpredictable. No one can be entirely sure what will happen from one moment to the next. Sandy, a US policewoman, was on the high way in Hanover County, Virginia, traveling to the airport. She was going to take on a fight to Ohio, where she was looking to carry out a special duty.
While Sandy drove her car smoothly, something unexpected happened. The vehicle in front of Sandy, for some unexplained reason, ran out of the roadway at full speed. With the brakes never hit, the car hit a tree badly. Sandy, who witnessed the crash, stopped and approached the vehicle. She wondered whether the driver was OK in such an accident. From the broken window, Sandy saw there were three persons in the vehicle: a mother and her two young children.
“As I approached the car, I could hear a lady screaming, ‘Help! Help! My children are there!’” Sandy recalled. The car was damaged seriously and Sandy found it really hard to open the door of the vehicle. Some smoke began to appear. It seemed that the vehicle might get on fire or, even worse, explode at any moment. After she was finally able to open one of the vehicle’s doors in the back, Sandy noticed the two children totally panicked, shaking all over. And the mother who was stuck in the seat was still screaming, “Help please! Get my babies out of the car.”
Sandy sprang into action. She freed the two children from the vehicle and got them to a safe area, away from the crash scene at once. When she was sure that the two children were not injured so seriously, she let out a deep breath.
Paragraph 1
One of the children asked Sandy, “Are you going to save my mommy?”
