Quote from Lorelai in Written in the Stars
Lorelai: Okay, but think about it. Why do we need the word "potty"? Is it really that much harder for a kid to learn the word "bathroom"? Rory: I don't know. Lorelai: "Timmy, do you have to go potty?" Or "Timmy, do you have to go to the bathroom?" See? Interchangeable. Rory: Not exactly interchangeable. Lorelai: How are they not interchangeable? Rory: To go potty is an action. To go to the bathroom is to go into a specific place. Lorelai: And I hate the word "potty." Rory: Well, what did you teach me to say? Lorelai: "Bathroom." Rory: You did? Lorelai: Yes, of course. Rory: I'm 2, I come up to you and I say, "Mommy, Mommy, I have to go to the..." Lorelai: The room where legends die.
