The Null Device
10 tips for Japanese travellers to the US, covering the Americans' culinary and sartorial customs, leisure activities and their (somewhat impoverished) vending machine culture, among other things:
In Japan, hip hop clothes are considered stylish. But in the United States, it is wise to avoid them, as you might be mistaken for a member of a street gang. The entire United States does not have good security, unfortunately. However, the difference between a place with good regional security and a “rough area” is clear. People walk less, there is a lot of graffiti, windows and doors are strictly fitted with bars. And young people are dressed in hip hop clothes that say "I want you to pay attention to me!"
If you put your bent middle and index fingers of both hands in the air, you are making finger quotation marks. It means you do not believe what you are saying. You can also say, "or so called."
In America, when men or women laugh, they do not turn away. They face front, open the mouth, and laugh in a loud voice. This is because in America if you muffle your laugh or turn away while laughing, you give the impression that you are talking about a secret or name-calling. It is nasty.
