When you first arrive in your assigned country, the first few minutes can be shocking. The air smells different, the people surging around you are likely different, the looks of buildings and storefronts and wares for sale may all be different.
If you are in modern country, such as Japan, you will likely feel only slightly uncomfortable, as the airport will be clean and streamlined, although perhaps twice as busy as you expected. But signs will be in English, and you will have no problem navigating through the airport to the outside world.
If you are in a third-world country, the airport could be a far cry from anything remotely comfortable, with military soldiers everywhere, a crush of people, strange maybe even repulsive smells in the air, total chaos. If you are alone, this can be especially intimidating.
When I arrive in a new country, I am always surprised at the first few moments outside the airport. The sky looks different, the air smells different, the chaos of people coming and going is different. Finding a bus or taxi or jeepney can be a fun experience but it is more likely to be a trying experience, so it is best if someone can meet you and help...
