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?

Her behaviour was poor but I think she was trying to be joking with you.

Yabu for not filling the mug, my mum she's this and I have to go and top it up. I fill mugs to about 1.5-2cm below the rim, like this (I don't know why my tea is frothy!)

That's not Tea. That's watery bubbles🫣 I'd lose my shit if someone gave me that😆

SuchiRolls · 25/08/2025 18:14

I’d just go and poor a bit more water in mine if it were me. I’d tell her to get f’ed if she ever thinks she’s coming to my house and speaking to me like that again, over me making her a coffee. As for the husband… Wtaf. If he’s got a problem with it he can make his own too. Ungrateful pair of twats!

TheTeasmaid · 25/08/2025 18:11

@CrashBambiCoot i know the feeling a friend is similar. i always make it about 3 or 5 cm from the lip of the cup to prevent spilling and they act like its holy trinity

If she is always visiting, can’t she just make herself a cup of coffee? That way she would make it just how she likes it.

BarbieinPNW · 25/08/2025 18:06

Tell the silly childish heifer to get her own coffee, apologize for for her behavior and if she can't treat you with common courtesy then stay her carcass at home

Glad it’s not just me! Solidarity, OP.

DH fills tea up, leaves the teabag in.

Then adds milk… Tea all over the counter.

Then spills it on the floor / coffee table.

I always tip some out when I catch him!

Also fills kettle to the max for one cuppa…

More solidarity here. Everything filled to/over the brim. He couldn't give a fook.

Youngcaza · 25/08/2025 18:06

Get her or your husband to make it next time she comes round, since they think they're so clever. Dont take that rubbish from either of them

Bonkersbilly · 25/08/2025 18:05

Get a new one from Rent-a-Sister.

It's not normal to fill it to the top, no.

But nor is it normal to leave it so short your sister and DH think you're giving them too little.

They'd be making their own damn coffee. Incredibly rude.

NorseHorse123 · 25/08/2025 18:00

She sounds unhinged- I wouldn’t allow her back…. Or if I did, she wouldn’t be getting any coffee!

Moii · 25/08/2025 18:00

Let her make her own

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.

I thought this. The way I would handle it is just have coffee at the kitchen table and put the caftiere on the table so she can fill her own cup. The whole situation is mental, but OP's sister does sound rude.

GiveDogBone · 25/08/2025 17:46

This story is almost unbelievable: repeated abuse, crazy dancing.

Now assuming it’s all true, then your sister is batshit crazy. Certainly ban her from the house and suggest she uses the spare time in her diary to go Starbucks.

I mean did it occur to her to ask for a second (in her view, half) cup? Or did she and you refused?

Robin67 · 25/08/2025 17:43

XDownwiththissortofthingX · 24/08/2025 16:57

Entitled? No, but as the post you've quoted makes clear, if it happened repeatedly then yes, it would be perfectly understandable for someone to eventually get sick of it and lose their temper.

So then fuck off and stop visiting. You can't turn up at someone's home and assault them with a (half) cup of hot coffee because it wasn't to your taste despite you repeatedly asking. There is no real world scenario where you are forced to accept a drink in someone else's home.

DilemmaDelilah · 25/08/2025 09:58

I would get an extra large mug (think Sports Direct size) just for her. And then fill it up to an uncomfortable level - not all the way, just too full to be carried comfortably. Then I would make her a HUGE cup of coffee and tell her, very sweetly and nicely, that you have taken her complaints on board and made her a full cup of coffee, but you can't carry it so she will have to pick it up herself. Then watch her struggle.

I used to get annoyed when I went to have a meal at my mother's and she only filled the (small) water glasses half full. I never mentioned it though - I wouldn't be that rude.

SugarPlumpFairyCakes · 25/08/2025 09:49

Sounds like perhaps you don’t really want your sister around much?

She sounds like a drama queen. And your h too.

Just be too busy to see her from now on.

TimeFlysWhenYoureHavingRum · 25/08/2025 09:33

Surely it depends how big the cup itself is.

ThreePointOneFourOneFiveNine · 24/08/2025 20:12

Well your sister is incredibly rude, but what I don’t understand is why you keep making her coffee. She’s a family member who visits three times a week, she can pour her own coffee surely? I wouldn’t expect to be treated like a guest in my sister’s house and I don’t visit nearly as often.

But if sis makes her own coffee she might fill the cup!

VeryStressedMum · 24/08/2025 20:58

Your sister was screaming and lunging at you over a cup of coffee and your husband joined in? They sound like a pair of utter psychotic idiots.

Laura95167 · 24/08/2025 20:45

What odd behaviour. I wouldnt invite her back

Firdbeeder · 24/08/2025 20:36

My husband does this. As he continues to do it despite being told my preference for a simple cup of coffee I have to assume he’s deliberately trying to piss me off so maybe your sister feels the same way. What’s stopping you doing this simple thing for her? You don’t trust her around your carpets?!

It is bad manners to overfill a coffee cup or a tea cup. I thought most people realised this.

Is she my DH in drag?

Depends how often you've handed me a half-full cup of coffee despite me reminding you every single time.

I'd give up long before that point and just say no to your offer of half a cup of coffee, but in a hypothetical situation where refusal isn't an option, then yes, eventually I'd lose my temper and you'd likely end up wearing your half cup of coffee.

yeah of course you would
