Sister is angry over a car

Stop dancing round her and feeding her madness. It is not normal to behave this way about anything let alone a car.

This really has to be the most ridiculous thing I've ever heard. Just get on with your life and forget about her, I certainly wouldn't be wasting my valuable time on someone so childish. She's unhinged.

Cars are produced to go on the market for people to buy. Manufacturers produce thousands of the same make and model.
I think your DH was daft and very mistaken to apologise to her for a simple, harmless coincidence.

Your sister doesn’t respect or value you at all. I would leave her be with her stupid, jealous rages. Don’t pander to it OP. You will never win with her.

Does she get road rage when she sees other people driving the same car?

She's a loon, stay away.

Someone in her immediate family should strongly advise her to see a doctor. She sounds unhinged and her immediate family members aren't helping her by going along with her batshit carry on.

She needs to talk to a doctor, something's a bit loose between her ears.

Her behaviour is a little unhinged considering she has deliberately refused to acknowledge the birth of her own nephew due to a car. Relatives have clarified it is the car that is the issue so it can't even be a misunderstanding. There is quite an age gap between you, is she the type that really resented you just existing and having to share your parents when you were born which has caused her unresolved issues?

Either way, I would find it unforgivable that a sibling didn't acknowledge the birth of my child out of their own resentment and would not want them in my life.

Crackers.

you are well shot of her.

who would want that level of nuts anywhere near their kids.
do her kids and husband realise it’s nuts?

you do not owe an apology
if anyone does it’s her for her bizarre behaviour

Go forth and don’t sweat it

They'd better not! Perfectly regulated women can rant and rage without the presence of a hormonal or neurological condition or upheaval, I assure you.
We must protect our freedom to be as batshit and as furious as ever we like, without triggering a flurry of diagnoses 🤣.

Send her a text saying DH got rid of the car and bought you a Porsche for Xmas

Are you sure she’s 50 and not 13?

She sounds nuts. Leave her to it. Do you really want someone so unhinged around your children anyway?

Unhinged and batshit.
Take this as a win.
You shouldn't want that type of crazy near your children.
Infact I would from now on refer to her with batshit as a prefix to her name.
You cannot reason with narcissistic behaviour like that.

Family that have had a chat with her have told me that I have copied her and she doesn’t like being copied

This reminds me of being 14 and seeing my classmates accusing each other of copying them by having similar rucksacks. Because if two girls in a small town bought identical Adidas bags, it couldn't possibly be due to coincidence 🙄. Is your sister a bit unusual in other ways too? Or, could she be envious of your pregnancies and looking for an excuse to reduce contact? Despite her "comfortable life", she doesn't sound very happy.

Batshit crazy.

I hate to break it to your sister but if she doesn’t like ‘being copied’ she probably also needs to get over the fact tens of thousands of people probably bought the same car this year too.

Even premium cars aren’t special - literally thousands of people but then every year.

She is trying to pin this whole thing on me.

Believe me OP, there is no "thing".

Have your family told her that she's ridiculous? Or is this yet another bizarre thread where everyone pussyfoots around unforgivable behaviour because they "don't want to get involved" or want to "keep the peace?

My blood pressure rises just reading this shit.

Does she have a history of mental health issues?
I bet she's lost a good amount of friends and family if that's how she reacts to such non-events. Unbelievable her husband hasn't divorced her and her daughter still speaks to her. No loss there for you though, she's done you a favour.

Loopy Lou is your sister.
Did you also name the child after her? Ha ha ha

Forgive yourself.
Don't dwell on the insulting way DSis is behaving.
She might just crack out of it one day.
Be ready to forget the whole thing if that happens.

Try not to feel offended and carry it on for years more. It is so uncomfortable for the whole family, not just you.
Enjoy your young children.

Has anyone mentioned menopause?

How could you copy off her if you didn't even buy the car?

She's acting like she created the car herself and you copied her newfangled invention. 🙄

What a freak. I think you’re better off just leaving her alone. She doesn’t sound like a sister that’s worth having. If she never talks to you again, it sounds like it would be a good thing. She doesn’t deserve you as a sister. I wouldn’t let her back in your life if she’s prepared to ignore the birth of your child over something so pathetically ridiculous.

So what if you have the same car! She's bat-shit. At one point four of my siblings had minis. Every family get-together there were jokes about The Italian Job. No one cared.

My dad has the same car as me. I love mine so much I recommended it to him when he was buying a new one. Because that’s what normal people do.

I would not apologise, I would leave her and be thankful about not having to have any involvement with her.

She sounds unhinged, you have absolutely nothing to apologize for, she can whistle for it, even if apologizing means "keeping the peace" bollocks to that, why should she hold everyone to ransom? She's acting like a bloody 5 year old..
