owt and Return my mum still says it. I actively asked her not to multiple times, as it really grates, I really find it infantilising and patronising tbh. Other UK acquaintances (tbh mainly friends of my parents and people I'm not really in touch with except chance meetings in the UK or Facebook contact) say it and of course I don't say anything. Friends from the UK don't say it as unlike family they actually process what's said in conversation and realise that home is where my life is.
People in my life here don't say it, no, though some ask if I'm going to go to my parents. I am not part of any expat circles but have lots of eastern European friends met through work and study, who have also moved here for good but have aging parents in their country of origin so understand the pressure and also have old acquaintances who do the "home" thing.
My friends live in a totally different part of the UK to my parents for the most part, which means no one part of the UK is home and seeing everyone in one trip is not really an option - I tried it when we first moved and it was stressful and unsatisfactory. I imagine this is true for a lot of mobile people - not many people move abroad straight from having lived in their hometown and nowhere else all their lives any more. It means no part of the UK is "home".
Yes, I'm staying here probably, at least until the kids leave home, unless something unforseen happens and we have to move to keep an income coming in or whatever. We're in Europe so the seasons are more pleasing and defined than the UK - warmer summers, snowier winters. Brexit prompted me to get citizenship, otherwise I wouldn't have felt a need; I suppose that solidified things...
I suppose you're right - this is mainly an expat thread not a broad living overseas thread. It annoys me personally to have my life reduced to an interlude with the expectation that it has to come to an end, that seems to me to be packaged up with the idea that others get to tell you that you're not at home in your home, but only in your parents' home town or the country of your birth (which is different for one of my kids to the other two, incidentally).
