I haven't decided on a prompt yet either. Or rather I've narrowed it down to two prompts. I have a variety of ideas for one, but nothing yet that forms into a story. The prompts are all very wide-ranged in their interpretation, which is good, but also makes it harder to decide on which way to proceed.

In addition I realised that I already have written a story that would fit one prompt, so I need to make sure not to repeat myself.
