How to tell a story, 3-year old version:

Start with "Once upon a time."
Then something terrible happens.
Then something else terrible happens.
As soon as sommething good happens, say "The End."

...Once upon a time, the two hand-spiders were chased by terrible bears and terrible snakes and had lots of adventures, but then they escaped and had cake. The end. For some reason, cake is the best thing that can happen in a lot of stories.
