I remember the day my sister started displaying her ways of acting. It sounds stupid at first, but if I had realized what it would lead into, I would have been more wary of her. We were 7 at the time and visiting the park. Back then there was a little girl, about 2 years older than us, she bullied me a lot for having a friend group that mostly consisted of girls. Anyway, on this day she was doing her usual routine of calling me a girl or gay or some crap, she punched me. Unluckily for her, my sister was there and saw the whole thing. After she walked away my sister gave me a hug and kissed my wound to try and make it heal, then ran to a bush.
I watched her as she rustled around in there for about 5 minutes until she pulled out what looked like a rock, a sharp rock. She then put it to her arm and made a deep cut. I watched in horror as she made several cuts like this, then ran to our mother rock in hand. I then saw my mother walking over to the girl's mother and confronting her while pointing at the girl who was bullying me. I remember her mother screaming at her while she cried. All this while I sat in the grass confused. Later that night after we got back from the hospital my mom said that my sister had run over to her saying that the girl had cut her. She also said the girl's mother had said that the girl would be giving her allowance to my sister for the next 2 months. Me, being the submissive and quiet child I was, I did not say anything about what I had seen and decided revenge was sweet.
From that day forth my sister just seemed different. Like she was changed somehow...I had noticed her acting more violent. I'd find maimed teddy bears in our closet, if we had steak she would squeeze the blood out of it into a bag, and one da our family dog disappeared under mysterious circumstances (we later found it's leg in the trash). If I'm being completely honest with you I was a stupid kid and didn't suspect anything, and quite frankly forgot about it over the course of a few years. Until our first year of high school...
