RORY: I am sick, I’m ill, I’m cracked. This is not who I am. If I were to write this down in my diary and I would read it, I would be like, Who is this freak? This isn’t me. This isn’t my diary. I wouldn’t do this. I wouldn’t skip school when I have finals coming up to go see a guy that isn’t even my guy and end up missing my mother’s graduation, which I wanted to be at so badly. That’s someone else. That’s someone flighty and stupid and dumb and girly. And, I mean, I missed your graduation, which is the worst thing I could have possibly done. I mean, I hurt you and I had to spend hours on a stinky bus next to a guy that was spitting into a can, just thinking about all of the minutes that were going by that I wasn’t at your graduation and they were hurting you, and they should have been hurting you because it was so selfish of this person who wasn’t me to do what she did.
Rory’s snap decision to go to New York is something she can’t explain logically, so that she says she must have a physical or mental illness. Not only has she let her mother down badly one one of the most important days of her life, but she skipped a day of school in the lead up to final exams, and it was to see a boy who isn’t even her boyfriend (and her boyfriend wouldn’t be thrilled to hear about this, which he won’t, because Rory has got into the habit of not being truthful with Dean).
Rory’s tearful, extravagant apology and her description of how bad she feels and how much she has already suffered for her actions has the effect of negating any of Lorelai’s feelings, or allowing her to tell Rory how she feels – because however unhappy Lorelai feels about Rory not turning up, Rory feels a million times worse.
It would be quite manipulative if done on purpose, but I think it is done in all innocence and sincerity. However, it’s very unfair on Lorelai, who now has to put aside not only her own feelings, but all the positive feelings she has about graduating, and focus on Rory’s problems.
Rory’s behaviour must seem horribly familiar to Lorelai. A teenage girl acting reckless and boy crazy, making foolish, selfish choices, and behaving in an irresponsible manner? She’s starting to sound an awful lot like Lorelai when she was a smart private schoolgirl.
Note that Rory speaks here about writing in her diary as if she actually has one – she doesn’t say, “If I had a diary”, or “If I wrote this down in a diary”, she says, “If I were to write this down in my diary”. There’s a strong suggestion here that Rory has a diary which she writes in regularly, which seems completely in character for her. I’m guessing the entry for this day would be very painful to write.
