You were David Tennant's child, no more than five years old. Often times, since David was in the middle of filming Doctor who, you didn't have anyone to care for you while your mum and dad worked. So, one of them often had to take you to their workplace. You were a fairly well behaved kid, so it proved to not be a big problem.
Today both David and Georgia had to go to work. And David decided to take you on set. You wouldn't say what happened anyway, you were a baby practically! So, right now you were watching David get his hair done as you munched on some crackers. You had completely free range over the food there. Of course you delighted in eating all the sweets immediately.
When he was finished, David walked over to you in his big trenchcoat, with a soft grin. "Hey, love. How are you doin'?" He asked, softly.
