I'm a 14m and have 7 other siblings and my older sister is 16 and she's been doing a lot of things, Drinking, Smoking and I'm 100% sure she's also doing Drugs plus she's a bully and wannabe gangster,My mother knows all this and Acts like she doesn't,Back on track, My mom and I with my other sister(28) Driving to pick up my sister Mia(The asshole sister)She took the wrong bus and was stranded at a McDonalds , while on the drive to get Mia I told my mom "Mom you gotta check Mia she's been doing a lot of shit and Acting like she runs the place and has caused a lot of things"My Mom shrugged me off and I pushed further,She finally started talking and said"Sit your little ass down you don't know how to parent anything so don't tell me how to parent"Something important I think should be known my parents always left us at home with our niece and Little brother so we basically had to take care of them,so I bought it up and she got mad,She hasn't spoken to me in a while,So reddit Aitah?
