(M15)So recently, i was blamed and being screamed on for forgetting one of my sister's trainings which i was supposed to take her to (for context she's 10 and the training is like 500m away, divided from our street by a crosswalk). My parents usually put all of the responsibility for her on me because im her older brother and im supposed to take care of her. Shit like this always happens, and she knows EXACTLY when the trainings are she just doesn't bother to remind me because all she does at home is watch TV.. i should probably mention that my mom did indeed call me like 1h before her training to remember to take her to it.. it just slipped out of my mind and now they're taking away my laptop, console, pocket money and grounding me. I kind of feel guilty because i forgot but i'm pretty sure i'm not responsible for her every move because she's not a toddler anymore. So am i the A-hole for being mad? edit: my parents are both lawyers so they usually work like 10h a day (8-5) so i kind of understand why i gotta parent her
