I find if I have nerdy stuff, people are more likely to talk to me. xD Whether I want it or not. There are a lot of younger cosplayers who think that the gatherings at Balboa or Seaport are the best thing and it means that they can do whatever they want. Unfortunately that also includes messing around with people and things they have no real business touching.
Ayaasan, you have such nice cosplays that I'm surprised you don't have millions of photos all over the place. xD
Cosplays of the future:
Sansa Stark 
Agent 13
