The Doctor: Yes. Yes, I have
actually rebuilt a TARDIS before, you know. I know what I'm
doing.
Idris: You're like a nine-year-old trying to
rebuild a motorbike in his bedroom. And you never read the
instructions.
The Doctor: I
always read the instructions.
Idris: There's a sign on my front door. You
have been walking past it for seven hundred years. What does it
say?
The Doctor:
That's not instructions!
Idris: There's an instruction at the bottom.
What does it say?
The
Doctor: "Pull to open."
Idris: Yes, and what do you do?
The
Doctor: I push!
Idris: Every single time. Seven hundred
years. Police box doors open out the way.
The
Doctor: I think I have earned the
right to open my front doors anyway I want.
Idris: Your front doors? Have you any idea how
childish that sounds?
The Doctor: Oh.
You are not my mother!
Idris: And you are not my
child.
