Possibly, I'm Insane

Rose’s kids are not good at waiting. It is not one of the skills valued by time travelers.

Rose buys them Advent calendars and brings them back to the TARDIS. The kids are utterly perplexed.

“You open one of the little doors each day of December,” she explains.

“But,” Brem says, nose scrunched up with thought, “why not just open them all at once?”

“That’s not the point. It’s for counting down each day to Christmas.”

“But we could just skip ahead to Christmas,” Athena points out quizzically.

“I vote we just open every door now,” Fortuna proposes.

Rose sighs.
