As a Canadian who lived outside the country for a few years, I would say that most Canadians* are ignorant of the unwritten rules that underpin our culture, just due to the fact it’s hard to see the arbitrary choices that lead to our current society without deeply experiencing another.

It’s not malicious, it’s misunderstanding.

Ask for feedback on your perceived missteps (prefer “what” and “how” questions), and you’ll likely get answers. I also believe that it will lead to a learning opportunity for both parties.

* I would add that you could replace “Canadian” with any identity that has any sense of isolation.
