In the words of a city kid

This week we read a book (which I'll review soon) about an Amish family, that includes a section where the protagonist, a young girl, is learning to milk a cow. Elisabeth described her perception of that section of the book in these words:

"She squeezed the cow underneath, and the pee pee came out."

I explained to her that the girl was milking the cow, and that it was milk coming out, to which Elisabeth replied,

"Then they must have to clean it!"

I guess that's what it means to pasteurize and homogenize.
