My graded story-starter!

In writing, we have a writing prompt we have to write about at the beginning of class, and it isn't a very long story, its just a story starter, but this is what I wrote:
         
        "Quick, build whatever you can, lets get out of here!!" howled George Kingman, the mayor of a small city. They had heard that a raging storm was going to trample through their compacted city. They planned to head East, to the beautiful meadows. The weather there was satisfactory, and the small creek that snaked through the long, golden grass would provide them with plentiful water. Plus, the water there was never to hot, nor to cold, so on the blistering hot days, the children could splash in the brook without burning their small and bony  shoulders.

         Taadaaa!!! Oh, and by the way, I got an A plus on this little test thing!!!! :P
