Just wanted to rant about my sister and ask advice on how to deal with people like this because I'm having trouble getting through. We have been temporarily living together for the past couple months whilst she waits to close on her new home. I know this sounds childish, but its honestly so deflating trying to reason with someone who is stubborn and refuses to take the blame for anything!!
Scenario 1: She offered to cook dinner last night and I told her theres some chicken in the freezer that needs defrosting. Come dinner time and I saw her serving up rice and lentils and I ask wheres the chicken. She says she 'forgot' to defrost it. This is not the first time its happened so I told her that I don't appreciate that I have to be the one who prompts her to do things (she's older than me!!). Her responsive is that I have more time to think because I've recently been put on furlough. After this she refused to talk about it anymore as she claimed I'm creating an argument 'out of nothing'.
Scenario 2: I ask her if she can take the christmas tree down (for the third time) as I was the one who put it up. She told me to 'not start' as she wanted to enjoy her breakfast. I decided to leave it because I know I'd be accused of starting an argument.
Scenario 3: (sorry this is TMI) but we have been having issues with our bathroom upstairs, it doesn't flush poo down. So I told her to use the downstairs loo for that from now on. Over the past 4 months I have walked into the upstairs bathroom and her poo is unflushed. I understandably get annoyed because its gross, and her excuse is that the downstairs toilet is too cold. I told her thats a selfish mentality and you guessed it... I'm 'starting an argument' and she refuses to talk about it anymore.
However, this time I stood my ground as this was the third time in 24 hours that she tried to dismiss me. She does this thing where she will just go silent and not respond to what I'm saying, and I'm obviously annoyed and want a response. So I was looking in her direction and she told me to 'stop staring at her with my bug eyes'. This is not the first time she has commented on my eyes, she always teases me for it. But this time I told her that she is mean and she takes low blows and that I never pick on someones physical appearance in an argument even if its a joke and she has the audacity to turn it around on me and say that if I wasn't staring at her she wouldn't have said it. I was shocked that she blamed me for picking on my physical appearance and I said that she's so stubborn and can't just take accountability or say sorry and she said 'neither do you'. Which is not true and she knows it so I asked for an example and she couldn't give one. I ended the argument saying that I find it hurtful and all I want is an apology and she said I should apologise to her for starting on her for the toilet issue.
I'm at a loss. Does anybody have experience trying to get through to someone who responds to arguments this way? Her default mechanism is to deflect the blame onto me. It's like accepting the blame or taking accountability is physically impossible for her. How do you get through to stubborn people? Any advice would be appreciated.
