What's the matter? You should be glad to be going home!
The Earth isn't my home, Sarah. I'm a Time Lord.
Oh, I know you're a Time Lord.
You don't understand the implications. I'm not a human being; I walk in eternity...
What's that supposed to mean?
It means I've lived for something like 750 years.
All right, so you're middle-aged!
Yes! About time I found something to do than run around after the Brigadier!
