Family responsibilities can become complicated after divorce and remarriage, especially when parents, school schedules, and childcare expectations collide. Miscommunication, personal responsibility, and unexpected accidents can quickly turn into serious family conflicts. In this story, a teenager questions whether he should accept blame for an incident he believes was caused by poor planning rather than his own actions.
My parents are divorced, and I'm their only child (16M). My dad is still single, while my mom remarried. Her husband has a 10-year-old daughter, who is now my stepsister.
I split my time equally between both parents. One week I'm with my mom, the next I'm with my dad. Honestly, my relationship with my dad has always been much better. My mom has always expected a lot from me.
One thing that constantly causes problems is that she texts me during school and expects an immediate response. She'll ask me to stop at the store, pick up takeout, walk my stepsister home from school, or take care of other errands while I'm literally sitting in class.
My dad and several of my teachers encouraged me to silence my phone during school hours and check it afterward. I started doing that because it was affecting my classes.
My mom even called my school once demanding they make me return her messages. I wish I were exaggerating, but I'm not.
Since she remarried, she's expected even more from me. She often wants me to walk my stepsister home or escort her to activities because I don't drive. One time she even made me wait outside my stepsister's basketball practice for over an hour just so I could walk her home afterward.
Back in April, I had an after-school activity. I left my phone on silent and didn't check it because I knew there would probably be another request.
When I finally looked at my phone, I saw several missed messages. My mom had texted saying I needed to pick up my stepsister from a Girl Scouts camping event. There was also a missed call and a voicemail where she was screaming because she'd received a call saying my stepsister had been knocked down by a bicycle and taken to the hospital.
When I got to my mom's house, nobody was there, so I did my homework and waited. A few hours later, my mom came home and told me my stepsister had decided to walk by herself because nobody came to get her. During that walk, she was hit by a bike.
She ended up with one broken leg and significant damage to her other knee, and doctors believe some of the injury could be long-term.
My mom immediately blamed me, saying that if I had answered my phone, none of this would have happened.
I told her I didn't think it was my fault. I never agreed to pick my stepsister up, and she already knew I had after-school activities. She argued that family should always come before school activities.
She also blamed my dad for supporting my decision to keep my phone on silent during school. My dad strongly disagreed and told her she shouldn't be putting that responsibility on me.
Since then, every week I'm at my mom's house, we end up arguing about it. She says I should feel ashamed for refusing to accept responsibility. Her husband completely agrees with her, which honestly doesn't surprise me because we've never had a good relationship.
I genuinely feel terrible that my stepsister was hurt, and I hope she fully recovers. But I don't believe I caused the accident. I was never asked in advance, I never agreed to pick her up, and I wasn't even aware she expected me to.
From my perspective, the adults should have made proper arrangements instead of assuming I would be available without asking.
So, AITA for refusing to accept the blame?
