Why am I writing Short Stories?
I don't know... But I write them all the time. Most of them are Fairy tales.
A Fairy tale is a type of short story that has a shared folklore. Fairy tales have not a moral ending, like a fable, nor a legend, which requires belief in the tale. Historical Fairy tales rarely have a happy ending.
Here are two really good quotes on fairy tales.
“If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales.”–Albert Einstein
“Fairy tales do not tell children the dragons exist. Children already know that dragons exist. Fairy tales tell children the dragons can be killed.” - G.K. Chesterton
