"Integration" is a nice high level and therewith also fluffy concept imo. Integration into what ? and then I do not mean that I have to drive my car on the other side of the road in for example the UK, and how to tip money when I pay my beer. Integration means that you would be able to describe the culture and traditions of a country ! Well... you can describe a lot of things that are indeed very practical in avoiding upsetting other people, or having unwanted & unexpected side effects. But if you live in a normal country you have already between your autochtone people a lot of culture sets... so you need not so much that common denominator, but the most frequent culture elements and traditions (and taboos). An ocean of fish when you integrate into an urban area. And hey... surprise surprise, foreign migrants "integrate" much better in urban areas than domestic mobility "migrants" from rural areas of the same country (at least in NL). And I did not even touch upon foundational culture. Still struggling with that And if I cannot properly describe that in words for myself... how do I explain that to others ?
