Crack
Anna scowled as the wheel of the shopping cart found a crack in the floor of the supermarket and she nearly fell. This was a hazard, she would report it to the manager, she thought. But suddenly the floor began to rumble and the lights flickered. She froze in panic while mayhem ensued; others shouted and ran towards the exits. And yet she couldn't move.
The crack in the floor spread to several feet wide. A shelf of pickles toppled and crashed. And yet she stood still as the floor shook and the crack continued to grow. An entire grocery aisle tumbled into the void. This caused her sense of self preservation to outvote her panic response, and thus she left the store.
Outside she was hit with a chorus of sirens while cars sped past and crashed into each other attempting to flee. She joined a crowd that was calmly watching and taking cell phone videos, each hoping their earthquake footage would be the hit on social media.
The crack was now two hundred feet wide and the building was collapsing. In a matter of minutes the entire grocery store was swallowed into the earth, the power lines cracked and spit out sparks as the wires were torn away. The onlookers were impressed, they had been there to witness the beginning of the end; for this was the day the earth inexplicably broke in half, and it all started under the wheel of Anna's shopping cart.
