Quote from Lorelai in Always a Godmother, Never a God
Rory: What is wrong with you? Lorelai: It's not like I really care, okay? It's not like I was gonna call you up to chitchat or make a date to go shoe shopping or something. But shouldn't a mother have a way to contact her daughter at least in case of an emergency? I mean, what if I was in a accident and had to have a blood transfusion? You're the only person in the world with the same blood type. It would really help to have your phone number.
