Erin: (comprehension dawning) Wait, do you mean to tell me that you just bought two gallons of TWO PERCENT MILK?
Noah: (knows he's in trouble) Yes.
Erin: (with emphasis) He's only supposed to drink WHOLE milk!
Noah: (incredulous) Says who?
Erin: (with righteous indignation) Oh, I don't know. EVERY MEDICAL PROFESSIONAL WHO'S EVER DEALT WITH A CHILD IN THE HISTORY OF THE WORLD.
Noah: (holding up hand) Let's not talk about this anymore.
Erin: (huffy) Fine. But you're going to have to go out and buy two gallons of whole milk tomorrow.
Noah: (without irony) I hope you have an appetite for dairy this week.
