I seem to have lost my actual story, but here are some tips I used to write it:
1.
Begin by describing the setting- This only has to take up a line or to but you should use lots of adjectives- maybe some metaphors or something too.
You don't need to actually state outright what the setting is- what you're trying to do is create an
atmosphere.
Eg "A thin shaft of silver moonlight peirced the darkness, illuminating one small patch of carpet in the centre of the room."
Don't be afraid of using pretty language- but dont try to use words that you are not comfortable with either.
2. Your next sentence or sentences should
introduce the main character- once again you don't have to be direct about it.
Eg. "To Dave's tired eyes, accustomed to the darkness, it seemed like a silent thunderbolt had struck the room, unbearably bright."
3. Then you can
explain more about the character- why they are there, what they are doing, how they are feeling. You can also introduce other characters.
4. After that, description is no longer so important- using too much flowery language isn't good. So just get to writing about
the events taking place in the story.
It's good to have a complication, rising action, climax, resolution etc but don't be too worried- it's only like a page and a half story.
You should always have some kind of conclusion though- and if possible make it an
original conclusion. Best to avoid "then I woke up", "happily ever after" etc.

Anyway hope I helped. Good luck
