Sophie had always been one to follow her principles, and today was no different. She needed to make a decision about her future, so she decided to retreat to the quiet of the woods. As she walked along the trail, she spotted a statue of a doe standing precisely at the center of a circular spot. The statue's skin seemed to shimmer in the sunlight, and she wondered if the sedimentary shift in the soil had caused this effect.
Suddenly, an asteroid crashed down from the sky, causing a flurry of debris to rain down around her. Sophie heard the cries of a child caught in the attack and knew she had to defend the defenseless. She quickly acquired an acorn, burning it to create a smokescreen that helped her approach the child unnoticed.
After the asteroid attack, Sophie concluded that it was important to always be defensive in the face of danger. She knew that her decision to defend the child had been the right one, and it had helped her to elevate herself in the process. She got back into her craft, feeling decidedly more confident than before. As she rode the elevator back to civilization, she thought about the combination of events that had led her to the right spot to aid the child in need. She knew that this experience had yielded a positive result, much like the computation she would do on her computer later to calculate the number of calories in her cereal.
