I Hate My Sister

Megan was playing her N64 and I was trying to ask her a question but she was too busy playing her stupid game to answer so I got angry and threw it out the window. She didn't look surprised though cuz I always did it. So then I threw her precious wii U out the window. Then she started to cry and she called me a bad sister! Then I got really angry and jumped on her, then she walked into the TV and it fell on her phone. Then she hit me and started to cry. But then mummy came and she punished megan for breaking all that stuff and hitting me. She's tried apologising but why should I talk to her when she attacked me?
