Write a short story-
Starts with woman sitting in restaurant, waiting for the man she's eating with to come back in from the outside, where he's on his cellphone. She can see him pacing in front of the place, talking on his phone, through the windows that line the front.
Rules:
The woman must interact with a server (at least once) at the restaurant, but you can use no dialog at all in the story- internal monologue (thought) only. The man does not come back inside or get off the phone during the story. She doesn't know who he's talking to. The man must be (your choice) a past, present, or potential lover (as in, they're just dating but aren't really a "couple" yet).
Everything else is fair game so long as the rules aren't broken. Just try and stay away from an infidelity storyline... too easy.
I find that prompts with exceedingly (annoyingly?) specific rules can be the most fun, because you must stretch your range and dig deep to come up with a unique storyline.
Have fun, and I look forward to your response.
