Hi everyone so I just kind of stumbled across this website and would like some perspective and advice on my situation. I'm feeling quite upset about this as this has been an ongoing situation in my family.
I'm a 17 years old girl and I live primarily with my 14 years old sister and my mum. My dad works away a lot but we all have a decent relationship with him. I love my dad but one thing about him is that he would never disagree with my mum even when he tells me he does think it's not right.
Anyways what's making me quite upset is my mum's very different expectations when it comes to my sister and I. Now I understand my sister is nearly 3 years younger than me so it's reasonable to expect less from her. My problem is there is significantly less expected from her compared to me 3 years ago.
Since I was 12, I had been expected to contribute to chores at home, which I think is reasonable but my sister is now 14 and still isn't expected to do anything. Usually my share is the laundry and unloading the dishwasher on weekends. And groceries shopping like every 2 weeks (we are lucky my mum's a stay at home mum). I have no complaints about this, but the thing is my sister is not only not expected to do anything, she also dumps her things on the corridors, in the living room, and never bothers to take her dish to the sink after meals.
I have talked to my mum about this and she would tell my sister to do it once, and my sister would ignore her and my mum would use that as a reason not to expect her to pull any weight, as she wouldn't listen anyways. Yet, every time I don't do a good job on my chores my mum would tell me off. Also, if for example my mum take the trash out and I don't replace the garbage bag in time she would think I don't want to do it and would tell me off. She also complains that I don't do enough around the house. Every time it leaves me feeling indignant because my sister has never once been held accountable by her to even not leave her stuff everywhere or to put her dish to the sink.
My sister is also very unkind; a lot of times when my mum cooks dinner for us she would call it disgusting to my mum's face, criticize the food, then leave some on the plate and just leave everything on the table, including used tissues. She does whatever she wants and she watches her iPad all through dinner every night, blast music out loud frequently. She insults me and picks fights with my mum and I and gets away with all of it.
If I even do half of what she does my mum would definitely be very cross with me. It hurts the most when my mum tells me off for not doing enough chores and not even expect my sister to do the most basic things. My mum says I just need to do my part and what my sister does is irrelevant, and I understand that in principle but practically as a family when this happens I feel unvalued and very unfair. My mum just thinks a mature person wouldn't feel this way. AIBU?
