Post-Holidays Writing Exercise

Happy 2018! For some, today marks the end of the holidays and the beginning of getting back into a work routine. Here's something quick to get your thoughts moving again:

This is an exercise inspired by Dylan Thomas that I wrote a while ago. In it, I ask you to begin with a prompt, then follow the natural stream of your memories from there. (If you only have a few minutes, you can do it without reading the Thomas piece first.) 

If you're writing fiction, try this: do the exercise with your main character. Pretend she's the one receiving the prompt: What memory does it trigger? And what follows from that memory, and from the next one? Keep writing for the whole fifteen minutes; don't censor yourself, just keep going.
