 'I absolutely fell in love with this girls. let me tell you something: I am from Romania and here is only the sixth series running bunt every other day that is on USA TV I check the internet and download it from there, so i am in line with the rest of the world. I can not believe how deep I am in this show. I become to know absolutely everything about them I looked on the internet what\'s Rory\'s car what are their middle names and stuff like that: Rory is also Leigh and Lorelay is Victoria. I can not understand why but my boyfriend does not like them and I try and try to make him see how wonderful they are but without success, but he does understand me and lets me be with my "obsesion" with the Gilmore Girls. I adore them. I really hope that if someone see\'s this will give them a try : You won\'t regret it')
