What I Did on My Christmas Holidays by Sally Sparrow (short story)

What I Did on My Christmas Holidays by Sally Sparrow was a short story by Steven Moffat originally published in the 2006 Doctor Who Annual. It was later adapted as the TV episode DW: Blink, again by Moffat. It is also available online via the BBC's Doctor Who website.

Summary
Sally Sparrow is a child who is contacted by the Doctor after he gets stuck at her mum's party after the TARDIS burps. The Doctor then precedes to write messages under Sally's wallpaper in her room and he sends her a video containing messages to Sally from Sally's mum's party.

Characters

 * Ninth Doctor
 * Sally Sparrow

Story Notes

 * This story was later adapted into the TV story Blink. The character of Sally Sparrow remains, but was changed into an adult. The same premise of communication across time using pre-recorded messages also remains, as does the idea of the Doctor separated from the TARDIS.
 * It is the first and, to date, only piece of Doctor Who short fiction to be adapted as an episode (a New Adventures novel and a Big Finish audio drama have also been adapted for TV).
 * This is the only officially licensed Ninth Doctor story in which the Doctor is not depicted as travelling with Rose.

Continuity

 * Placing this story in established canon is challenging. The Ninth Doctor is travelling without a companion, yet DW: Rose has the Doctor meeting Rose Tyler for the first time, with dialogue regarding his appearance implying this is not long after his most recent regeneration. While it's still possible this story takes place before the events of Rose, it's also possible that, just as DW: Attack of the Graske takes place while Rose is briefly on her own, this story takes place during an interval in which the Doctor, for reasons not mentioned, is similarly temporarily separated from Rose Tyler.
