Maybe you guys have more experience persuasion and discipline. It's kind of a personal family matter. If you care for this kind of thing then I appreciate any response. So I have this sister who's in her 30's now. I and the rest of the family struggle to live with her because she doesn't lift a finger in the house. She has this dog and she doesn't take proper care of him. If any of us approach her she lashes out in an immature way yelling and screaming like we're all against her. If I refuse to do any chores in order to get her to do them, the house becomes a disaster and everyone else starts complaining. I have to basically do all the chores just to keep people happy and I wish my sister would just be responsible enough to help out ONCE in a while. She can't even do that. Her room is literally a garbage dump. Carpet stains. Pee stains. Poo stains. Laundry everywhere. Dishes and mold and god knows what else. She won't clean it no matter how much my mother yells at her. When she leaves for work, the rest of us have to look after her dog who pees in the house all the god damn time no matter how many times we take it out. We can't blame it because it's my sister's fault for not taking it out on longer walks. This shouldn't be our responsibility. Not only that, she brought the dog home even after my parents said no. I don't remember the last time she did the dishes. Maybe a year ago? She expects everyone to be happy around her but doesn't understand we spite her because she's so irresponsible. She's literally like a 14 year old in a 30 year old body. She buys things on special occasions and takes us out for meals and stuff, which is nice. But she thinks spending money automatically sets her free from responsibility of any kind. I'm honestly tired of this family arguing all the time so I just shut my mouth and do all the chores. My dad is working almost all the time and my mom is tired of supporting the family all her life and getting disrespect from my sisters, so she barricades herself in her room. So basically I have no idea what to do. This is no way to live.
