Sister went nuts over a cup of coffee

509 replies

CrashBambiCoot · 24/08/2025 14:19

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?

It is in my house, otherwise you'll get told straight.

Nothing worse that looking forward to a cup of coffee and you get handed 3/4s of a cup.

Why not just have second cup?

If you know she likes a big cup of coffee, either fill it up or buy a bigger mug! What a ridiculous argument to have. YABBU.

Friendlygingercat · 24/08/2025 15:39

When I make coffee (in a mug) I leave about 3 cm from the rim. If my nephew makes me one he leaves about 4 cm. I never comment on this and would consider your sisters behaviour rude and belittling. I would probably tell her to go home and make her own coffee and would certainly be restricting her visits for such behaviour.

kleverklogs · 24/08/2025 15:38

She sounds utterly bizarre to me. And the fact your DH joined in even more so. They sound about 8 years old.

It's especially annoying when the mugs are smaller than you're used to, as well.

At MIL's I always had to make myself a 2nd cuppa, because her mugs were small and only 2/3 full. She bought a "big" mug specially for me, which was very sweet of her, but it's still smaller than the ones I use at home, so I still find myself wanting more tea or coffee.

And to make matters worse, her coffee is piss-weak instant and barely drinkable, so I always have tea, which is harder to fuck up.

Next time she's here, I think I'll make her a big pot of my rocket fuel espresso so she knows what real coffee's like.

It drives me crazy when people only do cups filled 1/2-2/3. If I wanted a tiny coffee I’d ask for a tiny coffee. If you are making a a drink, you fill the receptacle to about 10- 15mm from the rim ( unless there is a legitimate reason not to. I ask my DH for juice instead of coffee or tea, he brings me half a glass. He’d be bloody gutted if I made him a mini pizza for dinner instead of an actual adult meal but here I am supposed to be happy with half a drink.

Then make your own f*ing drink you moaning myrtl lol

See, that’s what happens when someone you love makes you a drink - you like it anyway.

I think this needs a scaled diagram to be able to give a considered response.

Yes, I suspect there is a great deal of hyperbole in the description of her behaviour. If she actually did exactly as described I’d have been straight on the phone requesting emergency assessment for a sudden psychiatric episode. It’s so unhinged that there’s no way you’d just carry on as if it hadn’t happened. Hmm

Exactly 🙄

Wishihadanalgorithm · 24/08/2025 15:35

I would not be making either her or your DH a hot drink again. Your sister sounds like a fucking lunatic.

Why is she around your house three times a week? I think bad behaviour should not be rewarded so I’d be out/too busy to see her for a while. I bet she will kick off about that as well but that’s her prerogative.

BTW my DP often leave a bigger gap at the top of a hot drink than I do. No has died so far!

OtherS · 24/08/2025 15:35

I fill mine to the top as if I do it in the machine and froth the milk, the milk is thick and doesn't spill. For some reason I don't register that non-frothy milk isn't so well-behaved so overfill when I make instant, and spill it a lot. If good friend / family underfilled it I might top it up myself, but I wouldn't start yelling at them and trying to make them spill it. That's very weird.

whitewineandsun · 24/08/2025 15:34

Also, why is she in your house that much? Imagine doing that and then taking the piss out of you. Put some boundaries down.

Mayanatalia · 24/08/2025 15:33

Your sister’s behaviour is the main issue here regardless of how much coffee is in the cup. If someone made a coffee for me, it could literally be half full and I wouldn’t act like that. And your husband joining in with her is odd, they both sound like a pair of tw@ts.

DeborahKerr · 24/08/2025 15:33

she's unhinged. I hope she doesn't have any children.

Tell her and your DH to fuck off

Yep!
How bloody rude of the pair of them

jwoo23 · 24/08/2025 15:33

Solidarity OP. My FIL is the same. Fills to the brim then sloshes coffee all over my new carpets as he walks up the stairs. Although he’s been told countless times. It’s unbearable. He’s the same with a pint in the pub, holds the glass at an angle that the beer is teetering on its way out and down the person next to him.

With the coffee it’s like he deliberately does it to goad me now, saying ‘see, I didn’t spill it’ as I watch him doing exactly that!

ThatCyanCat · 24/08/2025 15:32

Well clearly this isn't actually about coffee. It's exactly the kind of deranged, ridiculous, escalated displacement insanity that would happen in my family though.

She actually ‘screamed’? Screamed in your face about coffee? Really?

As was I - who knew hot drink entitlement was a thing? But turns out it is!

I say that sitting here drinking a warm-ish cup of ginger tea because my lovely mam went to make me one and forgot the kettle had boiled because she was distracted by the cat. So I have a warm-ish cup of ginger tea - it's not horrible and if I wanted to top it up with hot water then I can get off my bum and do it.

BlueSlate · 24/08/2025 15:30

On the surface, this sounds like a ridiculous reaction (the sister).

But I've been around the block enough times to know that people can retell stories like this that sound utterly unhinged until you hear the rest of it.

Basically because, most people tend to make drinks how other people prefer them rather than doggedly insist on doing it one way - so what if she wants more coffee? It's easy enough to accommodate. But also because it would be unusual for someone's sister and husband to over react so spectacularly over something so trivial.

It was a ridiculous reaction but to an already ridiculous scenario.

I suspect there's a bigger picture here.

bumbaloo · 24/08/2025 15:30

She screamed at you and shouted in your face?
is she suffering some sort of personality disorder?

Catcatcat111 · 24/08/2025 15:30

This is really weird. Surely if she’d drank her “half-cup” and wanted some more you’d make her another one? It wasn’t rationed? She sounds unhinged.

sandwichlover93 · 24/08/2025 15:29

doodleschnoodle · 24/08/2025 14:24

Is she unwell? That’s insane behaviour. The correct response when someone makes you a coffee is ‘Thank you’.

I don’t think it’s insanity, think she’s a see you next Tuesday 😅 (lighthearted response - I agree, it sounds unhinged!)

It's not the coffee.
Your sister and husband are bullying you.
Put a stop to it.

I agree with this.

You're being bullied and it's awful your 'd'h joined in.
