RORY: Because you should’ve seen the look on Grandma’s face when she asked me. It’s just really really important to her . . . Now if it’s that important to her, and it’s not that important to me, then why shouldn’t I do it?
A key difference between Rory and Lorelai comes up again. If someone she loves wants her to do something, and she doesn’t absolutely hate the idea, Rory will usually do it, whether it’s go golfing or sign up for a debutante ball. Lorelai’s response to her parents’ requests is usually, “Why should I?”, rather than “Why shouldn’t I?” (she wouldn’t even go to her relative’s funeral).
Lorelai is mystified by Rory’s desire to please her grandparents, but she has learnt her lesson from the fight they had over golf. This time she supports Rory’s decision completely, doing everything she can to help (albeit with lots of snarky comments).
