A bad beginning and a good ending (open)

I had it with my sister. She was rude,mean,and stupid. All she cares about is herself me me me me! If I could I would cut her throat at this very moment. The words she just spoke rang in my head You'r a weakling Kaygha I was through with her for the day,but what I did next supriesed me I took the throwing knives out of it's place and threw 2 at my sister. There were collective gasps all over the room,but I didn't care I just marched out of the training center not even looking back at my sister to see if she was alright or in this cause injured. I decided to go grocery shopping for my mom,we needed to go anyway after training so why not get over it now?

As I was leaving I heard footsteps following me. Probably Henri are oldest sister telling me to go back and apologize to my sister. I didn't wan't to and I didn't care about how much trouble i would get into back home.
