Santiago says he will clean all the merchant’s crystal overnight in exchange for money to get to Egypt. The merchant replies that the trip to Egypt is so long and expensive that Santiago couldn’t earn enough for the trip in a year. Santiago feels disappointed but agrees to take the job.
Very interesting! Here's an idea. Since you have only about 200 words right now and 400 words left, try adding a bit more to the beginning of the story - it will give more of a thrill, instead of jumping right into strange behavior. A little trick to add in more words is to use even MORE descriptive language - But you've done well already.
You can use inspiration from short thriller stories online or from a library- im sure you'll be able to find something. also think about the ending - will it be a good ending, or a bad ending? If you have, i'm sure you'll do great.
This probably isnt much help, sorry :)
