We live overseas and are very happy here, but I thought I'd write all the things I miss about the UK and love doing when we go back twice a year:
eating indian and thai food
having lunch in a pub garden in the summer
shopping (being able to browse in large shops like WHS without just asking for a pad of paper over the counter and getting what you're given)
gap for kids and monsoon
English books, mountains of them, that you can pick up and flick through in huge bookshops with cafes
cricket and rugby (well that is DH's actually, not mine. he does regret that our DS will never know the finer points of cricket. apparently if you don't learn it at school, you never really understand it)
not feeling like a second class citizen every time you speak (because no matter how fluent you are, you will always be 'foreign').
knowing the system (whatever system it is - education, health, how to queue in a bank)
