Write your OWN short story

Start like this:

Oh, it was to be so jolly! What a game! Such excitement thy hadn't known in years. The children catapulted this way and that across the green lawns, shouting at each other, holding hands, flying in circles, climbing trees, laughing. Overhead the rockets flew, and beetle cars whispered by on the streets, but the children played on. Such fun, such tremulous joy, such tumbling and hearty screaming.

Now you go on. Here are some questions to get you started:
When does all this take place? What do these children look like? Is there a leader in the group?  What is the name of the game? Who are they playing with?  Will it have any sort of consequence? Could it somehow spell danger? What about their parents? Are they paying any attention to their game? What happened in the end?


Note:
What I did not tell in class is that this is the beginning of a short story called ZERO HOUR by Ray Bradbury, a well-known American science fiction writer. It was published in 1951 and you can listen to it, if you like, as it was broadcast in 1955.
By the way check the meaning of ZERO HOUR here.
