To generalise your point further generally with the experience of living away from one's home country (or, even more, one's home culture): Aliens collect with aliens. Because of a shared experience. The shared experience is being alien. Very specific but common example: A local telling a taxi driver a location "next to XYZ school that relocated a few years ago". That's pretty clear to a local. However, "on the intersection of ABC and XYZ street" would be from a non-local. Don't think of this example as in taking a taxi, or finding a place. Of the assumptions someone intimately familiar with something, assuming others are so too. That's not true. You need to think and not, on un-thought assumption, not exclude.
