Quote from Rebecca in The Bar Manager, the Shrink, His Wife and Her Lover: Part 2
Lilith: Where is Frederick? I didn't see him in his room. Frasier: He's with your mother. Lilith: Fine. Then I'll just go and let you do whatever it was you were doing. [exits] Frasier: Lilith! Lilith! [exits] Rebecca: It was nice to see you again, Lilith.
