Why did i choose a short story for my brief?

At first when i was first given this task i decided i wanted to produce an advert as i thought it was the brief that appealed most to me and would interest me the most however as i began to research more into the brief the more i found it was not the best brief for me to produce as i was loosing lack of interest very fast therefore my final product would not be as great as something i had enjoyed looking into. Therefore the next brief that then seemed more practical and interesting to look into was short films as they show and explain stories to an audience in a different concept as to how films would present a story. Although it can be argued that i could of presented and done this through doing an advert due to most adverts tell a story so that it stays in the audience's head such as the John Lewis adverts are famous for their Christmas adverts as they produce a different plot to the story each year as well as Coca Cola, however i wanted to produce something that was merely based on a story that would intrigue the audience and then the outcome to be based on the story not to end with a random product. At first I started looking into documentary types of short films and thought that i was convinced with this genre however as i began to delve more into the genre i realized that there was not much that i could work with and I know what skills I have so therefore I knew i could not work with animation as i do not know how to use the software to produce an animation this then led me to making my own narrative short film. I now just need to work out what type of narrative I want to produce and then build an original story that will be induce my audience into wanting to watch it.
