Today we'll work with the good old 'how-to' genre. Write a 'list poem' (or a regular poem) or a piece of prose that explains various ways or steps in how-to do something.
Today's how-to is...
How to save the day.
Whether you write a guide to being a superhero, a realistic list of how to be prepared for any (or a specific) situation, you combine the idea of 'saving the day' and 'save the date' and discuss strategies to keeping a day open for an event, or even write a heartfelt recollection of a time when you, even in a small way, 'saved the day' by doing something that another person was very grateful for. Plenty of ways to approach this, have fun!
