House, Season 7

Cuddy:
I really do have to leave.

House:
I know.

Cuddy:
Then what's the problem?

House:
This isn't going to work.

Cuddy:
....that's it? You can't just say that and shut up.

House:
It's just a statement of fact, it's not a debatable proposition.

Cuddy:
Right...because you can see the future.

House:
No, but I can see the past and you're going to remember all the horrible things I've done and try to convince yourself that I've changed and I'm going to start doing those horrible things again because I haven't changed...then you'll realize that I'm an insane choice for someone who has a kid. And from there it's a short step to the inevitable conclusion that all of this...was a mistake. Tell me any of that isn't true.
