SirVix (and others) it seems to me that's fine if you're all happy with the same, you're happy to muck in with whatever they're doing, or stand by and chat while they do it, or accept that actually, while they're in the middle of cleaning the gutters, mending the car, studying, working at home, napping, or enjoying a rare and much wanted afternoon to themselves, that this isn't a good moment - so you'll happily sashay out and on your way as easily as you sashayed in.
The problem seems to be with people who aren't happy to fit in and won't leave but demand that everything stops that attention might be devoted to them. And, those who don't understand the concept of studying, working at home, napping or enjoying time to oneself.
In a way it's an introvert vs extrovert thing, the idea that having people around is always better than not is a uniquely extrovert perspective.
It also reflects an old-fashioned attitude of housewife as servant to the family, whose own time and wishes are not important, as serving others' needs always comes first and putting oneself first ever would be extraordinarily selfish.
Plus a shift towards people studying and working at home, rather than going elsewhere to do these things. There are endless threads on here about people not respecting WfH as actually working, so unavailable for childcare and social activity.
