Frasier: All right then. What seems to be the problem?
Erin: Uh... when we were at dinner, he was checking out another woman.
Lilith: And you feel threatened by this?
Erin: Shouldn't I?
Frasier: Well, maybe. Shot in the dark here. Your parents are divorced, Dad left Mom?
Erin: Yeah. How'd you know?
Lilith: It's classic transference. Because your father and mother split up, you overreact whenever you perceive a threat to your current relationship.
Frasier: [to Sean] And you, you care about this woman?
Sean: Absolutely.
Frasier: Then keep your eyes in your head! It bugs her, and it's bad form.
