There will be a boy at AnthroCon this year. He's about 18 years old. He'll be wearing what looks like a fishing hat with cheaply stitched white tiger ears stitched into the top. DO NOT ACCEPT A COMISSION FROM HIM! He'll follow you around, chase away other comissioners, and try to haggle the payment all weekend. Believe me, I know. His name is Nick but he goes by "Demetry".
Just thought I'd drop a warning from personal experience.
