Regarding knowing the laws of the country where you live.
I'm British and live in mainland Europe. I have fallen foul of the law here more than once, for things that I never considered might be a law.
For example, on buying a new car one must apply for a new registration number for the car. Not only would that not have occurred to me, it actually sounds quite illegal.
My MIL (from the country where I live) says I really should have read all the laws of the country and it's my responsibility to know the laws so I don't break them.
I totally agree with this in theory, but having to read a complex legal document that runs into hundreds of not thousands of pages to check I don't inadvertently break a law seems a bit extreme.
I'm not really sure how to frame the AIBU, but really to what extent should we know the laws of any country we are in, in order not to break them?
