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?

Wtf is wrong with both of them. If you ever do allow her back into your house she can make her own drinks. It doesn't matter a shit how you make coffee. She's in your house getting free drinks. She's being totally disrespectful. So is he. Why the hell is he on her side? Don't take any crap off either of them.

This isn't about coffee. Your sister sounds insane and your DH is a twat going along with it. Tell your sister she is not allowed over anymore and then tell your DH to fix his fucking attitude or he can get out too. Stop letting them abuse you.

(1) Tell your sister to make it herself since she always complains when you do it!

(2) Tell her you have run out of coffee!

(3) Don’t be home, go to a coffee shop with a friend instead!

Lots of options. Do not let her abuse you anymore. Good luck.

Is this for real???

Given the lack of update I'm guessing no

Rcgc · 30/08/2025 19:01

She’s is being unreasonable in her behaviour here. Could be more understanding of your reasons. But to look at this differently if someone said on multiple occasions that there wasn’t enough coffee in their cup. I imagine the first time was a casual comment. I would then just make their coffee with more in the cup! If I went to someone’s house and they knew I liked sugar in my coffee but never put sugar in my coffee. Eventually I would be like come on how many times do I have to tell you how I like my coffee with sugar.

It’s not about the coffee. It’s something else and she uses this to upset you not very nice sister.

Easy, next time tell her it’s her time to make the coffee!

IBEAN · 30/08/2025 18:55

I always fill mine to top for me or guests. I mean are you going on a hike before you sit down with coffee? Nobody wants a half cup. But I don't think that is the point here, clearly there are other issues.

Turbocharger · 30/08/2025 18:40

Charming lady. Reminds me of someone I used to work with.

ForLilacShaker · 30/08/2025 18:37

Your sister shouting over a cup of coffee at you, she's a very sad person

Noturgirl85 · 30/08/2025 18:32

Listen up people (ladies) if you have a HALF sister, she WILL sleep with your man!!!! #facts #truth #remember!!!!!

YanTanTetheraPetheraBumfitt · 24/08/2025 14:34

She was rude and no her behaviour isn’t normal.

saying that dh fills a mug up two thirds and it does annoy me 🤣

Made me giggle 😂

Smartiepants79 · 24/08/2025 14:30

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’m glad I’m not the only one. I really do have to delete my account because I am losing faith in humanity.

borntoweardiamonds · 30/08/2025 18:11

Get her a TommeeTippee and don't let her leave the kitchen until she drinks it all 😂

On a serious note, I had someone like that who loved nothing more than spilling drink & food on items in my home and she was soon on the banned visitor list once I realised she was always pi**ing on my chips on purpose!😂

Jayk12345 · 30/08/2025 18:06

Get a children cup for her, then fill it right to the top and out the lid on. She wants to act like a brat, she gets a brats cup. Id get the husband one too. What a pair of ungrateful Muppets.

TurtleShells96 · 30/08/2025 18:04

It's one thing to have a joke about it, maybe an inside joke but not to get hysterical over it. I'd be telling her where to go 😂 even so if you don't like it and she continues, then she definitely doesn't respect you

JoeBlogger · 30/08/2025 18:01

Tell them to make their own flipping coffee and give your husband a piece of your mind whilst your are at it. Both being very rude and he should support you not her. After all which sister did he marry?

SDTGisAnEvilWolefGenius · 28/08/2025 12:10

It is infuriating, I agree, @KittytheHare.

needsalotterywin · 28/08/2025 11:06

Is she Cathy from Two Doors Down?
Hideous 😡

This Op is a typical example of the kind that have been infecting MN lately. An obviously outrageous opening post, then abandons the thread.

See my post from yesterday at 10.19pm. The OP hasn’t been back because the whole situation is a manufactured pile of bovine excrement. She’s sitting under her bridge hugging herself with delight at all the trip-trapping going on overhead.

This is when I need the laugh emoji 🤣
... trip trap trip trap...
