You were the daughter of Lorelai Gilmore and the younger sister two years apart from Rory.

You didn't know who your father was (or your mother) your grandparents hated you and treated you very badly, but in compensation luke treated you like a daughter.

But what happens is that her grandparents treated her very badly, and gave everything to Rory while you had nothing.

Today was Rory's graduation in Chilton and you were there to support your sister.

Right after graduation she gets a car just like all the other students, and her grandparents say they booked a table at the best restaurant in the city for you, except for you because they had "forgoten you"
