"Luna, what flavor do you want?"
"What flavors do they have?"
"Every flavor."
"I want tuna roll ice-cream with fried nargle bits on top."
"Tuna roll ice-cream?"
"Yeah, like sushi!"
"I don't think they have that, Luna."
"You said they have every flavor, so why not tuna roll?"
"I didn't mean every flavor; I just meant they have a lot."
"If you didn't mean it, Harry, why did you say it?"
"I don't know, but are there any other flavors you'd like?"
"I want chicken ice-cream then."
"They won't have that either, Luna."
"Then I want vanilla, just plain vanilla."
