"So, when does the trick-r-treating start?" Kristoff asked Anna.

"Most years it starts around sunset," she explained, "but one year when we were kids they tried to change it to the middle of the afternoon. Everyone hated it and they changed it back the next year."

"Oh, are you talking about the afternoon trick-r-treating year?" Elsa called from the other room.

"Yeah," Anna said.

"Was it really that big a deal?" Kristoff asked.

"Yes," Anna and Elsa said simultaneously.

"If it was so unpopular, why'd they do it in the first place?"

"Can we not talk about this?" Elsa asked.
