Twelve
The Doctor has a diary.
With the regeneration, he'd forgotten about it until one day it "falls" off a shelf and smacks him in the head. He picks it up and the memories of everything he's written come flooding to the front of his mind: the pain, the terror, the anguish that only one who cannot die can feel. But then again, he concedes, others can't experience all the triumph, joy, and love contained in the old book, either. Besides, if the TARDIS is just going to keep bothering him about it, he might as well write in the thing again. He scowls – he'll do it but he doesn't have to be happy about it, he mentally tells his ship. This is just to get her off his back. Again.
He sits down in the library and, after a pen falls on his head a second later, opens the diary once again.
