Sidewalks packed with people, looking toward the ground, it's either negativitity, or heads weighing fifty pounds.
Maybe they look down so rain, will not get in their eyes, or maybe they're upset the sky, isn't always as colorful as sunrise.
It's easy to miss what isn't seen, but they'll probably find whatever they lose, they're missing almost all the beauty, but at least they have nice shoes.
Instead of always looking down, why don't they take a look around? They'd find interest in beautiful things, instead of perfectly tied shoe strings.
