Sister went nuts over a cup of coffee

my sister visits my house around 3 times a week. Every time she comes she takes the piss out of my coffee calling it “half a cup of coffee” etc

She last visited Friday where I made her a coffee and she snapped “oh come on, fill it up for fucks sake” saying I’d only half filled the mug (I hadn’t).

This morning she turns up. I make coffee, as I was taking it into the living room she looks into the mugs and screams “half a cup of coffee”. I snap back “I don’t fill it to the top so it doesn’t get spilled! Nobody fills coffee right to the top” so she started dancing around me acting crazy shouting “ooo don’t spill it” etc before suddenly lunging at me and shouting in my face - coffee got spilt.

Now I’ve said I’m not making her coffee anymore. That’s it. Sick of the piss taking and ranting and raving. DH witnessed all this and basically joined in with her. She’s 42, DH is 50.

its not normal to fill coffee right to the top is it??? And the hysterics is certainly not normal is it?

Get her a sippy cup just for your house, silly cow.

Best response! 😂

It's basically just bullying - from both your sister and your husband.

What sort of relationship did you have as children - did she always have tantrums at your expense and you got told off for it? There is something very wrong with the family dynamic here.

Don't make her coffee and don't make her welcome in your home.

JustPassingThruHere · 26/08/2025 15:22

Yes people fill it up to the top but people also don't go to anothers home making demands and being strange. Since she acted a fool, no more coffee and tell her to make sure if she brings her own, to use a container with a lid or don't bring it in.

I wish these types of things were my biggest concerns in life. How can I make the necessary changes?

I can't believe anyone would post something this stupid

I read these things on mumsnet sometimes and I just can’t really believe they’re real.
Whose sister actually repeatedly visits and is rude and unkind to them over how they make the coffee? And who allows it to happen more than twice without telling that sister to stop, make their own coffee or leave?
The whole thing is farcical and sounds like you’re both about 7 years old.

My thoughts exactly had a fil like this, he didn't do it me more than once. Your sister sounds unhinged.

ACatAsleepInYourHat · 26/08/2025 10:19

Nine pages and 426 replies at the time I post this, and the OP hasn’t been back once. I doubt her sincerity, to put it diplomatically. Undiplomatically, what utter bollocks.

They sound a pair of weird loons. Both would be our the door.

Depends who's doing the tidying up doesn't it?

In the situation I mentioned, it was half a glass of water over a hard floor surface. Friend's sister mopped it up straightaway but that was it...never invited back.

Lavenderblue11 · 26/08/2025 10:12

How desperate is she for coffee? Ffs, as others have said, she could have a second cup if she 'needed' one. This sounds like she's using this as an excuse to have a go at you. As for your husband being in cahoots with her, that's odd behaviour too, they're nothing going on between them is there?

WhereIsMyJumper · 24/08/2025 14:45

I don’t think it makes a blind bit of difference if you’re right about not filling the coffee to the top or not. What does matter is your sister treating you like shit in your own house after you’ve just made her a drink and your DH joining in…

@CrashBambiCoot This, OP. Their behaviour is unacceptable regardless to how much you fill the mug.

I generally do about 1-1.5cm from the top, more if there is a mobility issue for them.

Yes, I’ve sometimes gently ribbed someone for it being low by my standards, needing a step ladder, sometimes I remind them not to leave room for milk (as I don’t have milk and people are creatures of habit), but ultimately one should accept it with gratitude, if you’re really fussed, get up and top it up with a bit more water yourself!

I’d suggest OP, that you take a step back and look at the family you have, I suspect this sort of behaviour is not really new and that you’ve unintentionally allowed quite a lot of this in the past.

Develop your boundaries, learn how to assert yourself, and please don’t tolerate this sort of shitty behaviour from your sister again, in all honesty, I’d be tempted to go no contact, and certainly not from your husband!! He certainly needs a firm conversation, however, sadly, I suspect you may have one a bit like your sister. What you choose to do with that realisation is up to you.

Either way, they went too far. That was not ok. Know your worth.

💯 these are getting more and more ridiculous. How do people honestly get through life 😂

Correct gap

Bernardo1 · 26/08/2025 08:54

Can you not say "you're welcome to a 2nd even 3rd cup" ?

I'd also have yr husband make the coffee, when she's present. Require him to clear up any spills.

Trishyb10 · 26/08/2025 08:54

She,s ill or ignorant spoilt, if someone gave me a coffee i,d be grateful,is she jealous of you and wanting to pick? my sociopath bruv every time he came had to find fault with my whole life even when i was doing fine… keep her at arms length and discuss with hubby how wrong her behaviour is, stay strong, remember he who laughs last laughs longest girl x

Habibihk87 · 26/08/2025 08:53

Why is someone reacting they way over coffee. However someone serves you a drink they should be grateful. The cheek of it. And your husband joining in is not helping. Where’s the unity in that? Both need to grow up. Tell her she apologies or she doesn’t come back.

WatermelonGatorJerky · 26/08/2025 08:36

I really couldn’t give a shit how my coffee comes, or even if I get a coffee or not. I have bigger things to worry about. This is a very strange reaction to me.

Braygirlnow · 26/08/2025 07:45

If my sister complained more than once about how I made the coffee then every time she came I'd say "if you want a coffee help yourself". She is obviously bat shit crazy, but for your husband to then join in! That's awful op.

CasperGutman · 26/08/2025 07:20

I like a strong black coffee, like an Italian caffè lungo, so only half fill the mug usually. If be happy to make a guest a longer coffee like an Americano - but not if they were being a dick about it!

A sibling of mine who behaved like the OP's sister wouldn't be visiting my home for a while. If and when I did allow them back, they'd be making their own coffee and I'd insist they carry it around on a tray, pointedly reminding them they have form for spilling it.

Bagwyllydiart · 26/08/2025 07:09

That would be the last time she ever set foot in my house.

MrPickles73 · 26/08/2025 06:29

She sounds unhinged

Muffinmam · 26/08/2025 06:11

There’s nothing worse, is there?? Nothing else compares to a cup of coffee that is not filled to the brim? 🙄

MrJoeBangles · 26/08/2025 05:20

@XDownwiththissortofthingX 'Nothing worse'. Really? 'Nothing???

Magpie50 · 26/08/2025 01:21

Siblings can be right twats sometimes.
Just tell her to either make her own or bring round a supersized mug.

My family sometimes call my serving "A funeral cup" because I don't fill it all the way. But a little banter is one thing what your describing is hysterical. She wouldn't get back in my house if she acted like that.
