Smallville, Season 4

Lois:
Wow, she didn't take any prisoners, did she? Lana? Cute, smart, gutsy... and way too much for you to handle. I can see why you're in love with her.

Clark:
Look, you're really not the person I want to talk to about this.

Lois:
Suit yourself.

Clark:
It's just... I knew she'd be dating other people.

Lois:
But?

Clark:
I just don't understand how you could feel like you know someone so completely, like you know everything about them, and then just all of a sudden...

Lois:
You don't even know what continent they're on.

Clark:
[frustrated] Do you always have to finish people's thoughts?

Lois:
[equally frustrated] Well, am I right?
