When the World Turns Upside Down

When the world turns upside down, I’ll have to stand on air.
My heels will be over my knees, my knees over my hair.
Will the water stay in place or just come tumbling down
to fill up where the sky is now—where formerly was town?
Will gravity act just the same or will it pull us up?
How will it work when Grandpa tries to fill his coffee cup?
Will balls bounce up or down and will skiers ski uphill?
How will grandma’s old gray cat stay on the windowsill?
May I suggest the world stay just as it is instead?
It’s just too complicated standing on your head!
