To make up for the dark tone of my last drabble, I give you this small much more uplifting one. Jackie ponders on the unique sound the TARDIS makes.
Sound of the Universe
There was a sound that she always strained her ears for.
No one understood why she would suddenly drop a conversation and start running when the odd noise was heard, echoing through the streets with a thundering wail.
Most people, Jackie had found out, tended to think she was off her rocker. That the sound was creepy, frightening.
It wasn't to her.
To her, that wailing siren meant hope and laughter, tea and biscuits.
It meant putting up with him.
It meant Rose was home for a visit.
It was the sound of the universe.
And it sang for her.
