Dear [Имя друга],
You won't believe what happened at home today. My brother and I got into a huge fight. It all started because he took my favorite shirt without even asking! I was so mad because it's not the first time he's done this, and it really bothers me when he uses my things without permission.
He tried to apologize, but honestly, I was too angry to listen. I started shouting, and he got defensive. We ended up yelling at each other, and the whole situation was just awful.
I'm still upset about it. I wish he would just respect my things and ask before borrowing them. I hope we can sort this out soon because I hate fighting with him.
Anyway, how are you doing? I could really use a distraction right now. Let me know if you're free to hang out soon.
Talk to you later,
[Твое имя]
