Me and my sister have two major things in common: we're both loners and we're both gamers. My sister and I are best friends and extremely close. We even share a room together. So my mom woke us up for school this morning and she looked at me and said "I don't want to go." When I asked her why she told me a story: She was sitting alone at lunch like she usually does when boys from another table started calling her ugly and saying no guy would like her. She didn't cry or showed emotion. She pretended not to hear them and walk out of the cafeteria back to class. After she told me that she started crying saying she didn't want to go back there and that this isn't the first time. My sister told me that things like that have been happening to her ever since she started high school. But she kept it all to herself. One guy threw paper clips at her. They tell her to shut up in class. Whatever friends from middle school she had stopped talking to her without a reason. She cried and cried and all I could do was sit there and comfort her. She asked me to stay home with her (of course I would) and to never tell anyone else (I would never). I made us some coffee while she cooked pancakes. We watched movies and played BO3 all day. But I want to do more! I want to find those people and skin them! My sister and I have always had each others back so when I find out she's been hurting and I cant do anything about it, it enrages me! Are there any older brothers out there with advice? Because all of my plans end up with prison or a huge regret. Edit: Thank you all for your advise no matter how terrifying they were. But I'm 19 so I can't physically harm them without them hitting me first. They're all under 18.
