The Doctor had never really been a huge fan of Christmas decorations.
Of course, he had found them aesthetically pleasing, but he had never really taken to the whole idea of decorating, of spending all that time and energy on something that would only last a few short weeks, a time span that was mere blip in the entire scope of time and space. Granted, it was all very lovely; it was just highly impractical.
But now that he is part human, living in a house whose halls are proverbially decked with every type of trapping possible, he has begun to appreciate it in a new way. It isn't so much the act of decorating that matters, but the feeling it inspires. There is something to be said for the warmth of lights gleaming in windows, the glint of tinsel on a Christmas tree, the verdant swag of evergreen boughs on the mantle.
Yet his favorite part of the Christmas decorations, he decides, is the mistletoe. For, as he is finding out, a small sprig of the berried plant hung in a doorway is apparently inspiration enough for Rose Tyler to push him up against the doorframe and snog the life out of him.
"What was that for?" he asks when she pulls away, feeling a little more breathless than he would like to admit. "Don't get me wrong! It was lovely, just… unexpected."
"Mistletoe," she replies cheekily. "You're supposed to kiss someone if they're standing under it."
He glances upwards for the first time and sees the small sprig hanging above his head. So that's what that is there for. Interesting. The Doctor's mind kicks into gear. "And this is every time you meet someone beneath the mistletoe?"
"That's how it works."
"And," he continues, stepping closer to her, "correct me if I'm wrong, but hasn't Jackie hung this throughout the house?"
"Mm-hmm," Rose grins, her tongue poking out between her teeth.
"Last time I counted there were fifteen major doorways in this house."
"Well then," Rose says softly, tracing the line of his tie with a finger, "sounds like you'd better get busy."
He leans down to kiss her again, but she wriggles out of his grasp, darting a few steps away and laughing over her shoulder.
"Race you to the next one!"
Yes, the Doctor decides, Christmas decorations might be a bit of trouble, but when you think about it, they are absolutely worth it.
