Sarah felt something tap her on the shoulder and spun around. It was a boy who looked older than her sister. He asked where everyone was going. "Late huh? All the new people are going to the gym to be tested. Me and my sister are coming along to watch."
Sam did her best to stay out of sight of the stranger, and wished her sister did the same.
"So, what's your name? Mine's Sarah." She then pointed to her sister "And that's Samantha, my sister. She likes being called Sam though, don't know why, Sam sounds like a boys name."
Sam didn't look to pleased to be pointed out.
