Answer:
I am writing this essay to express my sincerest apologies for hitting my older sister. I understand that my actions were wrong and that I have hurt her both physically and emotionally. My behavior was unacceptable and I take full responsibility for my actions.
I know that as a younger sibling, it is my responsibility to look up to my older sister and to respect her. Hitting her was a violation of that trust and respect. I also realize that I have caused her pain and fear, and for that, I am truly sorry. I promise to work hard to regain her trust and to show her that I am capable of making better choices in the future.
Going forward, I will make sure to control my temper and to find more appropriate ways to express my frustrations. I will also seek help from my parents or a trusted adult if I need support in managing my emotions. I want to show my sister and everyone else that I am capable of being a responsible and respectful member of my family. I hope that with time and effort, my sister will be able to forgive me and that we can move past this incident.
