Struggling over handling a houseguest rebuff

MsAmerica · 16/03/2026 19:36

I’m not really asking about reasonableness. But I think that people unfortunately use AIBU as a catchall, especially for etiquette posts in the absence of an etiquette forum – so that’s what I’m doing. I’m just curious as to how you would have handled this.

I have a younger half-sister with whom I’ve never lived, but when I was in my teens, we saw quite a bit of each other, and had a nice big-sister/little-sister relationship. In adulthood, although we had a good time if we happened to be having dinner, she otherwise ignored my attempts to reach out to her. I don’t think she was deliberately snubbing me or being rude – she just didn’t care. Even when we were living in the same city, it wasn’t any different. If I sent her a birthday present, she didn’t acknowledge it. If I invited her to something, she didn’t RSVP. At one point several years ago, she stood me up for dinner, which we’d set up in advance, and I didn’t even hear from her until days later, when she said she hadn’t picked up her messages (which were the messages pinning down the time and place to eat). She apologized and said she’d make it up to me – but I never heard anything further, ever.

However, last year we happened to be lunching in the aftermath of the death of our family patriarch, so to speak, and she expressed a wish to be closer. Fine. I feel that she’s never been much on family, but maybe this death sparked some re-assessment.

Then a week or two ago, she left a message to say she had a business event in my city and wanted to stay with me for three days. I left her a polite message saying no, sorry, but I couldn’t.

Let me explain. First, I’m not a hostess type. Guests staying over make me very anxious, partly because I have no facility for whipping up great meals at the drop of a hat. Also, not only am I a bad housekeeper, at the moment my place is utter chaos, with mountains of paperwork piled high, and a bunch of things that need fixing, like leaky faucets and leaky toilets. Also, although I didn’t say it, I’m horribly allergic to cats, and she has two – and in case you didn’t know, cat owners inevitably carry the cat dander with them. This isn’t just my feeling - there are statistics showing that. So once she’s here, my place may be permanently contaminated. I thought it would be even more hurtful to tell her that, but maybe I'm wrong.

Meanwhile, she’s left two more messages, plaintively asking, why, why, why can’t she stay? After all, she said, we were going to try to be closer.

I understand that she’d like to save money on a hotel, but she has a solid income, and the trip is tax-deductible for her. And part of me is wondering if her sudden wish for closeness was due to her knowing she would be wanting a place to stay. Sorry if this sounds uncharitable, but after decades of her ignoring me, I don’t know that I’m suddenly obliged to provide accommodations.

So, I’m curious if any of you are good at delicate etiquette maneuvering, how you would handle something like this? Miss Manners says that when someone asks you “Why not?” you should just keep repeating, “Because I just can’t.” But I can’t come up with anything to say that would solve this kind of thing.

Ugh - sorry this is so long.

The moment you start to spin up reasons because she asked why is the moment you create a headache for yourself, and from the sounds of it not something that you owe her.
Shes a blagger and a CF.
Tbh, this would be a moment to look at the bigger picture, she treated you like crap over the dinner thing and at various other times as well. The whole ‘we should reconnect’ was nice to say at that moment but in light of everything else I’d question her sincerity. You can test this by saying nothing more than ‘It’s just not something I can do right now’ and offer to meet up for coffee/lunch/dinner. If she continues to badger you, rebuffs or ignores you, you’ll know exactly where you stand and how to deal with her going forwards.

Sorry, what's a blagger? Is that like a blaggard?

Yes, I'm questioning her sincerity a little, but even more questioning her follow-through. That is, I think most of us sometimes have good intentions, but just don't keep at it. I'll have to see how it plays out.

I'd say that by getting closer you meant building a relationship through staying in touch and meeting up. That this hadn't been the case for years because she didn't respond to you, so to suddenly go from nothing to three days in each others pockets would feel awkward. That you were keen to have a relationship, and would be happy to host her in the future once you'd built one again.
Because I'm a great believer in telling the truth rather than making excuses. Polite fiction and keeping your real reasons to yourself never moves a situation forward. You are in the right here, and if you've any hope of a relationship that is genuine and had mutual respect, you need to set your stall out. If she values you for you, she will accept that. If she doesn't, then it only confirms what you already suspect.

Thank you. Very well put.

A blagger is a cheeky person who is always trying to get something for nothing. Sometimes they try and blag you with charm but usually they're quite ruthless in trying to get something out of you that's only of benefit to them. Often lying to get what they want.

What?? I cannot imagine pressing someone for a reason why they wouldn't be able to host me upon request.

Puffalicious · 22/03/2026 08:42

I do think she's a CF. Deal with her as such.

However, whatever you feel about neurodivergent people, they do NOT have 'mental' problems or issues, they have brain differences. It's very different, & you come across as rather dismissive & ignorant.

Can I also just say that your writing style, whilst written in perfect English and to be commended, is very formal & unusual. Perhaps you come across this way in real life too, which is perhaps why you find communicating with your sister also difficult?

I hope that someday people wake up to the fact that just because I lot of people have something doesn't mean it's a desirable trait, nor a free pass. Same with, for instance, obesity.

I see all the indignation, but things like this are used, even when inapplicable, just to excuse something that shouldn't be excused.

👏👏👏❤️.

Wickedlittledancer · 22/03/2026 09:31

I’d not say something like please stop asking as it’s a no will put an end to the relationship, if that’s what you want go for it. People on here always go for scorched earth

just say look I’d love to see you, but the house isn’t visitor ready and it would me uncomfortable, but let’s do lunch or coffee.

Summerhut2025 · 22/03/2026 10:01

Yeah I would say I’m really sorry but my home isn’t suitable at the minute to host any guests but if you would like to meet up while you’re here that would be nice. Let me know when you’re free. Then leave it to her to arrange.
if she’s a CF and still tries to force her way in just reply No, it does not work for me, please do not ask again. Then block her as her plan will be to call you once she’s there with some ridiculous excuse as to why she has to stay.

Hm. And "blag" is a real verb?
Sounds basically like a sociopath.

I'm sorry if I gave the impression that I find communicating with my sister difficult. We chat up a storm when we're together. This was just an instance of an etiquette struggle.
For posting online, I try to be as precise and detailed as possible, my big problem being my poor proofreading. I wish others would do the same, as I get tired of people who ask for help with crucial information missing, or people whose grammar is so bad that I don't want to bother to reply.

There is nothing at all wrong or unusual about your writing style. I have no idea what the PP means by that.

You don’t have to have people to stay @MsAmerica

But you should sort out your house so it’s not impossible to have visitors

Yes, 'to blag' is a genuine verb used in the UK.
I blagged free tickets = I persuaded someone to give me free tickets
I blagged a drink off him.
My sister is trying to blag a free room.
All acceptable uses of the verb 'to blag' 😀

I can see another side to this: it sounds like there might be some neurodiversity in your family and some ADHD on her side. Her “pick up put down” attitude to relationships should not be taken personally, until you’ve had a conversation with her about it. At least give her a chance to explain. You are absolutely well within your rights to say no to her staying over, but do allow some space for both of you to come back from whatever this is. There is a small chance she means it - she wants to try. Imagine how lovely it would be if that were true - and on your terms too. Good luck.

Of course it’s ADHD 😆

Franjipanl8r · 01/04/2026 05:17

I don’t understand why you just can’t tell her the reasons you don’t want her to stay? They’re all valid reasons.

Ceramiq · 01/04/2026 05:42

I have a younger sister and tbh she's always been disrespectful - more than happy to let me pick up family slack but no attempt to be reliable. She's been like that all her life and was indulged by our DM ("different personality" according to DM, "spoilt" according to me) and thinks it's quite normal to treat her big sister badly. At some point you do have to draw a line.

LBFseBrom · 01/04/2026 06:37

If she has a business event near you, she would be able to stay in a hotel at the company's expense. She probably wanted to stay with you because she wants to see you, it wouldn't be to save money.

However I do understand your reasons for not wanting to host her. It might be best to be totally honest about them, including cat dander. You are not being unreasonable.

I don’t agree that people with adhd/autism or other neuro developmental issues do not have mental problems. I also find it offensive how so many people are so fast to dissociate their neurodivergence from mental problems. The fact is adhd/autism is an issue and it is based in the brain, ergo it is a mental issue. A person with ocd or an eating disorder also have issues that are based in the brain. They might not have a neuro developmental issue- but they might. Perhaps all mental issues stem from neurodivergence? Nobody knows. I find it as challenging to deal with my autistic brother as I do with my alcoholic sister- and I don’t view one as more or less moral or worthy or justifiable or whatever.

Buffalogruffalo · 01/04/2026 07:20

I forgot to add that I have adhd and I also have anxiety. And before everyone explains to me my anxiety is a symptom of my ADHD, I don’t agree and I personally believe my ADHD developed as a consequence of my anxious disposition.
lastly, these are very new diagnoses and the scientific rigour is not reliable so please spare me the over confident answers that tell me this is simple and clear cut. It’s not.

MsAmerica · 19/03/2026 03:48

Oh, gee, I post about a little family tussle, and your reaction is to suggest mental problems in my family? Thanks a lot.

ADHD is not a mental health problem. It’s a learning disorder like dyslexia is not a mental health problem it’s a learning disorder. And she is displaying ND traits. ND means your brain is different from NT - it’s physically different it doesn’t automatically mean you have mental health problems.

wheresthesnowgone · 01/04/2026 07:35

Why? Why? Why?

Because I don't have anywhere for guests to sleep.

thanks2 · 01/04/2026 07:38

Sorry but I think this is all daft. Just tell her the truth. You are trying to build a relationship with her - if you don’t tell her the truth anything less will look disingenuous. What’s the point of having someone in your life you feel you have to lie to to maintain the relationship?

”I do really want to see you, but I can’t have anyone who owns a cat in the house as I am extremely allergic to cats and people who own cats have cat dander on their clothes. Plus my house has some problems at the moment so it’s not fit for guests.’
