@Lockdownlumpy I REALLY wish you had put a poll. Bet it would have been a resounding YABU.
I agree with other posters. I HATE having people around, I HATE 'hosting,' and more than anything, I HATE not knowing when they're going to leave.
On the occasion someone virtually invites themselves (and yeah, we used to know several couples who used do that,) we put a caveat in.
E.G. if they came/wanted to come at 2pm, we'd day 'Errrrr, yeah sure come over then' (or come IN then if they turned up with no warning.) Then we'd say 'we have to go out at 4pm, but that gives us a couple of hours to chat..' So we knew there was a 'time limit' on it.
It was a bit harder if someone came in the evening though, as we obviously weren't going to be going out anywhere at 10pm! And some people didn't know when to fucking leave! Personally, I think 4 hours is a maximum someone should stay, and the longest I would stay, like 7.00pm to 11.00pm. Personally, I would normally think about leaving after 3 to 3½ hours.
And no, me and DH don't go to anyone else's either. Like many other posters, we prefer to meet outside, and have a coffee, or a pub lunch. (I also HATE going out in the evening. Much prefer late mornings/lunchtimes.)
We used to be more sociable, and have people over, and had lots of parties for DD, when 10 or 15 of her mates would come, and even 4 or 5 of the mums. And I was a huge social butterfly from 16-17, to around 40-42. DH was too.
But for the past 10-12 years, I (and also DH) can't be arsed. Lockdown has been a blessing for this. Haven't had to be arsed with anyone! I don't mean our adult DD, and very close family of course!)
One thing that DOES fuck me right off, is posters on here, berating people, and mocking them, because they don't want people in their house, and aren't keen on going to anyone else's house either. It's like the ones who don't want to answer the door to people; they are mocked and derided too. Can people just keep their sticky beaks out?
It's got fuck-all to do with you, what anyone else does.
Oh, and re; the OP... 'couple-friendships.' Ewwww.. I hate them. I HATE being friends with other couples. (I mean close friends, and in each others lives a lot, not just chatting when you see them!) Used to be friends with couples some years ago, and I hated it. Not least because it was almost always DH's friend and his wife!
He was HIS mate, and I was expected to be HER friend because of this. I never wanted it, and I never liked it, and neither did she. I had my own female friends (and a couple of male ones,) and didn't need DH's mate's WIFE forcing on me as a friend.
Finally, despite sounding like (and actually BEING) pretty anti-social, and a bit grumpy,) I don't mind seeing people/socialising now and again, but NOT IN MY HOUSE. Nope. That's my little sanctuary, where I feel comfortable and safe. I hate people being in it.. So what?! NEWSFLASH: people are different!!!
