About religion being a private matter, I wish my mother-in-law would practice that. She is super religious and british and it gets on my nerves sometimes b/c I am not outgoing about my faith, i am conservative and generally prefer to keep it very private.
About living in England - I get guilt from my family, but it's not that bad. I get upset when I go back home after a nice visit to America b/c i feel like i'm missing out on a lot, but in fact I'm probably not b/c I spend so much quality time with them when I am there.
Livign without Target is not easy. Living without a good walmart (asda does not live up) is even harder. Just knowing where to find what is the most frustrating thing in the world. I cannot wait until I am finally able to know exactly which store to go to in order to find a certain kitchen thing or decorative thing etc... In the US, I instinctively knew where to go, in the UK, it's a big hunt to find the right place.
Shoe shopping will never be as good at the US, imho. However, other shopping is alright and even better than the US in some circumstances.
I have started cook differently in England, I have had to adapt to their recipes a bit for DH, plus it's just easier b/c they have all the ingredients for more english-style recipes available. I still cook very American things too, but I don't cook very English while in the states.
I have completely adjusted to doing laundry without a dryer and sometimes feel guilty using one when I'm back in the US.
