He remembers when Susan was born.

He'd spent days of his first regeneration making her crib. It was commonly a father who passed down his old crib or made a new one to be passed down, but his son had died on another planet. Shot four times, twice pre-regeneration and twice during. Just after he learned he was going to have a little girl. Since it was just improper for a grandfather to pass his crib he made her one. To get passed down from her to her daughter, to her granddaughter. On Gallifrey a crib was something truly special.

By that point in time he'd had his TARDIS -hiding away as it was- stuck as a police box. An old, worn, blue as blue can be police box.

Commonly when a Time Lord made a crib it would be the burnt orange of the sky, the fiery red or the grass, or the deep purple of the clouds. Something that was taken from nature. Back then, when he'd still been Theta and not the Doctor, he made his granddaughter's crib a worn looking blue. Not like any blue that could be described, but it was the bluest blue he'd ever seen.

It took three days to cut the wood, get it together, then paint it the proper color. Worth every second, really.

A crib wasn't complete without the family symbols though. On the front the put his own name, the back the family's, and the sides his sons and step-daughters. They weren't the best, the paintwork a bit sloppy and crooked, but he'd never had much of a steady hand when holding a brush. He thought it added character. Susan's mother agreed.

The last touch was all his own, quite literally. His own father had made him a mobile. It had stars and planets and moved to the slightest touch, which had apparently amused him greatly when he'd been six months old. As a final touch he hung the mobile on the crib and went off to deliver it.

Susan was born two days later and he was positive he'd never be as happy as those first few moments, holding his granddaughter in his arms and thinking: She'll be great one day. She'll touch the stars.

Over eight hundred years later and he's still sure those moments had been his happiest. Even as he brings out Susan's old crib -his mobile still hanging from it- for Amy and Rory's daughter he knows his happiest day was when Susan was born and when he'd been making her that crib.

The close second had to be seeing Melody though.
