In a split second what could happen?

This is a promo I wrote in class

What can happen in a second for me would forgetting to read my book and the forgetting to mark my place in the book so I have to go through the whole thing to find the last place where I left off. Another second goes by and I haven't finished typing this sentence. Then another shall go by and you forget what you about to write and make stuff up, and make a good story. While seconds go by your life is getting shorter and shorter. In a second you could be driving down a peaceful road and then a herd of animals are on the road over the side of the hill. In another second you will be hurt while falling off a bike and having your knees bleed from the scrape of the pavement you had been riding on. In a split second a child dies while the adults aren’t watching over their infant. While more split seconds go bye you keep reading this story and begin to wonder why is this person writing this? In a second the computer saves this story after I stop writing. Another second goes by and the fan will be snoring and making others begin to fall under the calling of sleep. Another second goes by and this story still isn’t finished. In a split second this class will be over and then kids will begin flowing out of class and into a new learning cell of a prison. More seconds go by and you will get an email saying you have to go to work after school. Another second goes by and your classmates are still typing their journal entries. Soon your last second will be reading a story, or reading a chart in a bed. In a split second a car runs over your favored and beloved pet. Finally the last second goes by and this story still isn’t finished because I just don’t want to finish ha ha.
