my school is bored and everyone is looking for drama

okay so im gonna write down everything that happened so you guys understand. this all happened during September(as im writing this incident now its October) so you can tell this happened a long ass time ago. it was during our terry fox run/walk(yes im a Canadian how did you know😭) my sisters {im gonna call her kk} friend (im gonna call ss), ss was joking with one of her friends (im gonna call that friend ba) so ss and ba was just play arguing with each other both throwing playful insults at eachother till ss said ba was bald and apparently she didnt like that and got mad at her. so ss ended up apologising and everything was fine until one day in OCTOBER btw yes an entire MONTH passed since that happened. one day(last week) on thrusday a bunch of girls(like 20+) ran up to my sister you would assume a party is going on or smth and they started arguing with my sister and ss because they asked them if ss was good with ba and she said she wasnt sure because they didnt really talk after that. and thats when it alla started everyone was screaming at eachother even tho the situation was finished with LAST MONTH and it pissed me off so i got mad and was like why is there so much people arguing abt something that happened last month so i was like whos the victim(ba) and they were like "lets go to her" now i was confused because i though one of the girls there was the victim(ba) come to find out the girl wasnt even there nor did she know abt that so all those girls where js hungry for useless drama that was solved LAST MONTH!!!! so i got angry because they called my sister retarded and one of the girls threatened to throw hands and i was like all of this but the girl who was offended wasnt even there so obviously they were js looking for something to do. now my sister is in grade 7 and im in grade 8 and js so yk all the girls that were up in this "fight" are also in grade 8 and i was angry because you guys r grade 8s and acting like ur in grade 6 with this useless group drama that was once again im saying this for the tenth time SOLVED LAST MONTH i dont know how many times i have to say this happened last month and thats why i started getting angry at this one girl who was cussing out my sister because ur doing this to look cool not because ur standing up for ur friend. anyways since that happened LAST WEEK i was finished with it but some of my friends wanted to know what happened so i explained it to her and the girl i argued with had a friend (im gonna call snitch) well snitch heard me talking abt her and the situation and snitch went to the girl and she got a bunch of people and some guys too and started arguing with me and even tho i said sorry multiply times because i was confused on what she wanted from me i even told her i would bake her a cookie because she was very angry for no reason. anyways a bunch of people started surrounding and this one annoying guy kept asking us to fight even tho ik i could probably beat her up i dont like fighting because im not sure i would win. id probably fight if i knew i would win 100% so obviously i didnt want to fight her and the guy asked if i was scared ofc i was scared like cmon. anyways the bell ran as she and a bunch of other ppl were yelling at me i js went inside the school with the rest of my friends, honestly shout out to my friends bc they were standing up for me!
