Write about the awkwardest hookup of all time. Ideally, you’ll write about a hookup with which you were directly involved, but, hey, this is your writing practice, so if you know of a story about someone else having a terribly experience and feel like you want to write about that, go for it.
Better yet, make a list of hookups gone awry both yours and others’ and pick one. Save the rest of the list to your master writing ideas list for a rainy day.
