Lorelai: Why are you smiling like that?
Emily: What are you talking about?
Lorelai: You're smiling.
Emily: I'm happy.
Lorelai: That's not your 'I'm happy smile.'
Emily: Well, then what smile is it Lorelai?
Lorelai: It's your 'I've got something on Lorelai smile.'
Lorelai: Rory, your mother must be very tired.
Rory: She works a lot.
Lorelai: I grew up with that smile. I know that smile.
Emily: (to Rory) Tell me about school.
Rory: Well, my French final went pretty well.
Lorelai: You can change the subject. I know the smile.
Emily: Whatever you say, dear.
Lorelai: I used it a few times myself.
Rory: Mom...
Emily: (to Rory) So tell me about Parents' day.
Lorelai: What?
Emily: Parents' day. Next Wednesday. When all the parents are supposed to go to class with their children all day long.
Lorelai: The Chilton newsletter came out today!
Rory: Yep.
Lorelai: Right.
Emily: You didn't read yours?
Lorelai: Not yet.
Emily: Ah...
Lorelai: But you knew that.
Emily: Well...
Lorelai: Hence the smile.
