You can go straight through a stop sign or straight through an inheritance. Straight lines might connect two points or they might set up a joke.
Maybe you’re straight-forward. Perhaps you’re straight-laced.
Write a page that plays with the idea of straight. Don’t plan too much. Start with a thought or observation with straight in it and follow your ideas wherever they go.
When you reach the bottom of the page, reread your work, being alert for hidden or surprise connections. That might help you find an interesting title idea. Put the date and a signature on the page, too. And some illustration if you like.
