Ok, here is a shocker for everyone.
The UK, specifically London.
I’m English, I live overseas. I lived in London in my twenties and OMG I miss it!
I have no reason to go back as I have no family there any more.
I miss the food, the junk food, the theatre, the world class museums, the ease of access to those experiences, the great transport system (even though I lived there when Bob Crow was arranging strike after strike - still better than anywhere else). I miss the seasons, I miss the evening standard (when there were 3+ editions a day), I miss the pubs, I miss going out so easily after work, I miss everything being green.
I could go on but probably shouldn’t.
Edited to add - I’m several long flights away so I won’t be visiting any time soon but I want to and I plan to. As lovely as where I am is, I miss London and while I loved it while I was there, I think I appreciate it even more now,
