Creative task: If not on a wall, then perhaps underfoot?

“Make someone’s day” is one of the slogans promoted by Loesje. You can find more of them HERE:
These taglines can be encountered in the form of stickers and murals. Those that surprised me the most, however, were the ones “underfoot”—on promenades, sidewalks, and pathways. They are an intervention in the fabric of the city, only visible to those who looked down as they walked through it.
Now for the task. What would you write to someone, who, for various reasons, is walking with their head down? Take the first step—a chalky inscription is enough to make your slogan present in the urban/public space!
