I grew up in Liberia in the 80s and had to leave due to the civil war. (Remember General Butt-Naked? Yeah, that war in that country) It was a crazy time, not one big shock but a string of many smaller things. For example, I would look out the school window and see a horde of students wielding machetes overrunning the school grounds - I can't remember what they were protesting.
But coming back to Europe the biggest culture shocks were functioning waste disposal and utilities, and how clean everything was.
Also it was hard for me to relate to people's problems, because they seemed so trivial. Took me a while to adjust.
Yes! Being unable to relate to people's problems due to triviality was also something that I faced as someone who moved from a third world to a first world country.
Yayy! You understand me! I thought my comment appeared a bit asshole-ish and was almost thinking of editing it.
In Liberia I perceived a different culture of complaining. You'll get an earful of excuses. Much palaver and lamentation. But in the end, we'll work something out. We might be mad now, we might laugh the issue off, but tomorrow we drink together. Or maybe not. No biggie.
