You were David Tennant's child. It was a blessing, really, to be the child of what seemed to be the most kindest person on the planet. It also meant you went on holiday a lot.
David didn't really enjoy holidays all that much, he found them a bit stressful and he went around the world a lot as it was, considering his acting job. He got around a lot. But he of course still went on vacation, because it was still fun with you and your siblings, and of course your mum.
You'd just arrived at the airport, of course nearly four hours early for your flight. David immediately flopped down on a seat as soon as you reached some, with a big sigh. Your siblings already were looking at all the shops there were, trying to decide which to look at first. And so were you.
