I left the UK in 1977 and between 1980 and 1990, Thailand was home; Pattaya specifically, then it was about 12 years in the USA and Brazil. I returned to Thailand around 2007, settling down again, briefly in Pattaya before moving to Isaan. I visited the UK at least three times a year during those periods, more often when I was US based and apart from the Covid hiatus, still spent around 2 months per year in the UK. I only have a nice and nephew surviving there, and I see them every second visit. They are in their late twenties now and never bring up or talk about Britain being "lost" when we meet.
The UK has changed, some good and some bad, but I don't see it as dire and hopless as some here. Chances are that I will go back there for my final years.
