Kate: No, I am not going down that road again.
Frasier: 'Course you're not. Because at the end of that road is a cul-de-sac of vulnerability. That's not you, is it?
No, you're cement-hard.
Kate: "Cul-de-sac of vulnerability"? All right, listen. You see me for a couple of hours out of
every day, and you think you know me? The me me? All right, I can be tough. Okay, I've gotta be. I can also be tender, spontaneous, shy, lusty, playful.
Frasier: Kittenish?
Kate: I could climb you like a scratching post.
Both: Damn it!
[Kate climbs on her desk. They start kissing again]
