Donna could hear the Doctors cries of delight as she walked past one of the many doors of the TARDIS, she was on her way to bed, but the sound of the Doctor having fun stopped her.
'Wheee!' he cried happily. ' This is SO Much fun!'
Donna was interested in what the Doctor was up to, and she didn't want to miss out. She opened the door and the sight before her made her grin ear to ear, finding out what was causing the calls of delight from the Time Lord.
The Doctor was skating on the waxed floors of what seemed to be a ballroom. Dressed in his blue suit.
And socks. No skates, socks. He hadn't noticed her, he was having too much fun.
Until Donna took of her shoes, and sock skated up to him. She took his hand, surprised , he stopped his skating and cries of delight, and looked at her quizzically. Then beamed again.
'Donna Noble, I'm sock skating!' he proclaimed happily.
'I see that, you are bonkers!' she replied.
'Why do you have your socks on then, you are bonkers as well!' he retorted. Donna chuckled.
' We can be bonkers together, Sock. Skating. Come on then, Spaceman. Lets skate!' as they skated off together, hand in hand, calling out in delight in that ballroom with waxed floors.
