Oooh goodness! I remember my first NDK so well.. I was 12, and scared out of my mind. My friends had asked me if I wanted to go to an anime convention, and I kind of just shrugged. They ended up taking me, and I was completely overwhelmed.
I used to have an extreme fear of people, and I think NDK had the most people I've ever seen in my life. I was completely paranoid until I figured out, "Hey, these people are interested in the same things as I am.. this is pretty cool!"
Finally! A little redemption from being called a geek or a nerd all my life and being picked on constantly. :] I love NDK now, I meet so many new friends there, and it's always fun not to be a freak for once, but accepted.
