Imagine spinning a globe, dropping your finger on wherever it stops, then declaring that’s your next vacation destination. Hopefully you’re going someplace you’ve always wanted to see. But what if it isn’t?
Would you pretend that your finger didn’t hit that spot? Choose the one you really wanted? Or stay with the original?
Now place that globe before your protagonist. Why has she chosen this method for planning a trip? Is she adventurous? Foolhardy? Has she already gone everywhere she’d hoped to be and so is open to new, random choices?
What does she do if she’s pleased? If she’s disappointed?
Is this enacted in the privacy of her home or does she make a big production in front of family and friends? Doing so in public allows for tension, dialogue, comradery, and banter.
Include both description and dialogue, but especially emotions. After all, this requires seeing the emotions flash across her face.
Have fun with this one.
