I said, "Huh?"
The water, when it goes down the drain and through the pipes and to the tree?
"I'm not sure what you mean..."
Getting frustrated: You told me, Mama! The water, it goes down down down the drain into the pipes and goes to the sewage treating tree!
"Oh! You mean the sewage treatment PLANT?"
Yes, Mama! The plant!
I laughed my butt off. Of course plant=tree!
