"Let's stop showing our belly buttons and finish eating our dinner."
I put that in the same category as:
"Do not put that mermaid in the potty."
"Don't blow your nose on that wipe. You just wiped your front with it."
"I shouldn't have to explain why throwing yourself backwards in the bathtub is a bad idea."
"We do not stand on the laptop."
"Take your boot out of your mouth."
Sadly, these are all statements that I've made in the last few days. Even more sadly, some of them I've had to say more than once.
