I've lived in other countries a handful of times for fairly brief periods (no longer than 6 months), and it is really true. I've know some people who've spent years abroad, come back to the U.S. and nope right back out as fast as they can find employment back where they came from. It's not a statement about the quality of a place, but really having to go through an adjustment to get used to your new home and then hav…
Originally, it felt... very odd, every time I came back Stateside, especially when visiting the podunk suburb where my parents live (and incidentally, where I grew up).
Going from a city of 13 million that has quite possibly the best civic infrastructure in the world, to an aging and slowly dying town that barely breaks the 80k mark in terms of population is quite a transition.
I think the best way to explain it is... divergence? As in, my path, and the path of that place have diverged. Everything from before that point feels "natural", and everything afterwards feels strange.
Now that I've been an expat for awhile, and have bounced around quite a bit, that feeling of oddness seems to have vanished for pretty much everywhere I visit.
Sure, things are different in different places, but everything seems to fall into a slot of "this feels right" or "this doesn't suit my tastes", and there really isn't anywhere that has a perfect mix of everything.
Although I'll admit, the urge to return stateside has gotten quite a bit stronger over the years. I'm very comfortable in Japan, speak the language, and have a solid social network, but at the same time, I find myself missing a lot of the daily aspects of American life (especially the grocery stores!)
