THE GIRL WHO CRIED POTTY

One day we were driving
When Sister yelled, “Potty!”
So off-road Dad drove,
Then Sis whispered, “Nah. Sorry.”

One day Sis cried, “Potty!”
So Mom hit the brakes.
At the next gas station,
Sister giggled, “Nope. My mistake.”

Then one day Sis screamed, “Potty!”
This time Mom and Dad both said, no.
Only that time, we soon learned,
Sister really did have to go.
