Mum (What I Did on My Christmas Holidays by Sally Sparrow)
From Tardis Wiki, the free Doctor Who reference
In the 1980s, the Mum and Dad of Sally and Tim Sparrow attended Christmas parties at Sally's aunt's house in Devon.
Over Christmas 2005, she went away for the weekend with Dad, leaving Sally at her aunt's and Tim with Rupert.
According to her, Tim "wasn't planned". (PROSE: What I Did on My Christmas Holidays by Sally Sparrow)
