Donna usually didn't enjoy Christmas , preferring to spend it asleep .
Not until she met the Doctor. He was like a big kid at Christmas , he even had been wearing a santa hat upon his head for the past two weeks, everywhere they went, getting some strange looks too, especially when they had arrived in the middle of summer in Texas once.
She sat in front of the fireplace in the TARDIS library , she was just wishing that they had some stockings to hang, when the Doctor entered the room. He was carrying something in his hand.
'What do you have there?' Donna asked curiously, they looked very much like a pair of..
'Socks!' she breathed, as he waltzed over to the fireplace, and hung them.
'Yes socks, we needed stockings didn't we?' he asked. Donna just shook her head.
'They aren't going to hold much' she told him.
'Yes, they are. You never know, Santa may arrive tonight' he replied cheerfully. Donna just shook her head again.
'You do know Santa isn't real?"
'How do you know ? Christmas 1981 Donna Noble, who left that Cabbage Patch doll under your tree?'
Donna was actually surprised. 'Wait… it was you?!'
He turned around and grinned cheekily. 'Maybe'
'No!' she breathed, in amazement, as he sat down on the sofa next to her, the fire flickering cheerfully, as two red socks hung.
'But the socks Doctor, they won't hold much ' she repeated. He shrugged.
'Yes they will. You're forgetting Time Lord technology Donna'
'Bigger on the inside!' they exclaimed together.
