Apology Letters to sibling.
Apologizing for Name-Calling and Kicking

I’m really sorry for calling you a “poo head” and for kicking your bum. I know that was childish and hurtful, and I didn’t think about how my words and actions would make you feel. You deserve better from me, especially as your sibling. I realize now that spamming you repeatedly was annoying and disrespectful of your space. I should have been more considerate, and I regret not recognizing how my behavior could affect our relationship. You mean a lot to me, and the last thing I want is to make you feel upset or disrespected. I take full responsibility for my actions, and I want to assure you that I’m committed to doing better. I’ll be more mindful of my words and how I joke around in the future. It’s important to me that you feel valued and respected, and I want to work on being a better sister. I completely understand if you need some time to process this. Whenever you’re ready, I’d love to talk and hopefully clear the air. I miss our connection and can’t stand the idea of having put a wedge between us. Thank you for being patient with me while I work through this.
