HELP WTF IS HAPPENING

It was such a peaceful day, I woke up early and was having a good time, but that girl REALLY had to text in the group chat. Litsen, I'm not that kind of person to sit around and see someone insulting my loves ones. And when this girl was texting and fighting in the GC for no reason, saying things like how we weren't raised right, and how we deserve to die, ofc I had to say something. And no, I don't think I went overboard at all. I was being sarcastic and saying that I don't care. And that bitch really deleted every message whenever she cussed and showed the chats to her mom, and then, ofc the mom voice messaged us and she was cursing us 3 girls to "bully" her daughter and she wasn't event seeing her own daughter's voice messages. Saying she took screenshots and said that she's gonna show this to the principal. Who's the asshole in this idk...
