Intro -
When I was 15, I was asked to babysit my friend's little sister, Georgia. She was 13 years old and in my (and her) opinion, she was too old to be babysat. However, we were quite good friends, so we both just accepted it.
But anyway, I hadn't expected three things:
1. Georgia didn't like taking orders from people only two years older than her.
2. She had been taking martial arts lessons.
3. She was great at making malicious, evil plans in about five seconds.
I didn't know it, but I was doomed.
