Creative Writing Assignment.

I've been brain storming for my first creative writing assignment, which is supposed to be a fiction piece of 300 words or less. Interesting, with a solid plot, keeps your focused without spilling too much, includes a climax, makes you think. All in 300 words. The hardest thing about this, surprisingly, is the fiction part. I have alot of entertaining stories that are all true. I fear regret, not rejection, which makes for some bist mistakes and good anectodes.

So far I'm working on ten different stories and I can't decide which one to focus on and officially polish and finish. Here are the first sentences from the most promising ones.

1- "Black's is a nude beach, and there is nothing you can do about that."

2- "3 months and 40 lbs. later, I was their queen."

3- "She got on the bus and sat right next to Beautiful Basketball Boy, despite the bus having a grand total of (now) three passengers; the third sat two rows back and glowered at the newest arrival."

Let me knoowwww.....
