Ideas for a Short Film

I am currently in the process of thinking of an idea to produce for me short film product. Obviously, there are set 'themes' which the majority of short films follow:

• A conflict, big or small- a flm without out a conflict often has no base to the story.
• A story or anecdote you have heard.
• Something that has happened to you, possible exaggerated/simplified.
• A generic film
• A rite of passage story
• Subvert the audiences expectations
• A desire you have that either comes true or is thwarted
• A historic event
• A sense of closure
• A tale with a twist

From this list I have narrowed down my choices and will probably replicate the idea or either a sense of closure, a right of passage or a conflict.

I have chosen these, simply due to the idea that the others (such as historic event) are not realistic for me to make successfully with the equipment/props/places I have access too.
