Brits who dated or married non-Brits, what culture shocks did you experience?

I married a Polish woman and moved to Poland. On the big things there's not a huge difference, so it's less shock and more a constant barrage of things being a little bit different. Hospitality, gift giving, etiquette around hello/goodbye is far more important. I keep boxes of UK biscuits, chocolates and bottles of wine and spirits in the cupboard just in case someone drops in or I need to thank someone for something. If you drop in on someone there's an 80% chance of a plate of nicely arranged ham, cheese and tomato appearing in the next five minutes. What feels to be a near constant process of cleaning graves and putting new candles on them, to the point where I now have a box labelled grave candles and grave cleaner. I keep grave candles in the car in case we're driving past and see that a new one needs to be put in. How accepted second hand clothes are. There's so many second hand clothes shops and everyone I know shops in them including people with good salaries. The willingness for everyone to let you know their opinion on your child rearing. Which is actually quite fine as there's a lot more expectation that the nearest adult to a child will also tell them off and stop them doing something life threatening (dangerous is OK) Where I live everything does stop on Sunday. We were having a bbq today and a car drove along our road, we all stopped to stare at it wondering who it was and because it was the first moving car we'd seen for an hour.
