I am one

When I turned sixteen my whole life changed. The mark on the side of my neck started burning and glowing an ominous purple colour as my parents ran upstairs cheering. "I wonder what it's going to be" my dad boomed as he danced with glee. They had been waiting for this day since I was born and I wasn't going to ruin it for them now, even though I was getting slightly uncomfortable with the noise they were making. This was the day I was going to take my place in society, the day I could finally work, yet all I could think about was what food I could stuff myself with when I finally got downstairs. My parents clapped as the number slowly formed on my wrist, placing bets as to which number I would get. However, neither of us expected the number I got.
