Wow...you're so lucky!! I'm so envious right now. I have a Yuri autograph too from the NY fansign that my friend's sister helped get for me, but it wasn't personalized like yours. I'm still really ecstatic about it, but I also wished she wrote my name. My life would be complete!
Anyway, congratulations to you! All your efforts waiting for her paid off! She even spoke to you and the rest of the fans there. I shall hold on to the hope that one day I'll get that chance too.
