Just a few quick general observations from a foreigner(some good, some bad):
-Walmart is a fucking hilarious experience, watching minorities and white trash with their dumb ass kids buying stupid shit. The employee's are even worse.
-Americans in general above the age of 25-30 look unhealthy which usually reflects their obsession with bad types of food. They are either very fat or look like they're full of toxins with their pale horrible skin.
-Girls are either bottom of the barrel or SMOKING hot. Such a diverse amount of ethnicity so there's no real "standard".
-Never knew that saggy old, washed out, unstylish jeans could be so in style. Almost everyone except for hot college students had the most bland and boring taste in fashion.
-Very unusual and interesting architecture. Everything has more color to it. You can tell that the country is still young since there is not a lot of old buildings around. Everything is built around vehicles. I knew I was in America when I saw a drive-through Dunkin Donuts. (I caught a NYPD officer in the act of buying donuts, made me smile)
-I love the college partying scene, explains a lot about blinky's popular thread.
-21 years drinking age and 16 years driving is off the scale retarded. I think a lot of americans agree on this.
-American people ALWAYS smile in front of the camera, never saw them taking a spontaneous photo... Everyone always had to pose pretending to be happy.
-Never seen so many disclaimers in my entire life. Half the commercials are devoted to disclaimers. Never knew it was so dangerous to take a simple cough medicine

-All kinds of goverment info that I saw (signs, ads etc) presumed you were a retard. They always had to threat you with x amount of years in prison and fines if you broke this and that law etc. A lot of information or advises you got was to plant fear in you.
-People get fired a lot easier and quicker. Do your job properly or get kicked out.
-They ask you "wazzup" or "how's it going" not caring about the answer they get.
-Americans in general worry a lot about staying "PC" but behind closed doors I heard a lot of people saying "fucking n*ggers". Black people I met that didn't act "ghetto" could probably be counted on two hands. Nothing racist about it, just stating my experience. Everything jewish or holocaust is not to be joked about.

-No one dared say they are American. It's always "I'm half Irish and quarter Italian blabla". The country has been around since the 18th century and most of the immigration happened a long time ago, time to say that you're american, no?
-They are usually very sociable and devote a lot of effort to make sure their guests have a pleasant stay.
-American traffic is very calm and even though I'm not aware of all the traffic rules there is, driving around was not a problem. Every sign and traffic information was worded out for you. I did see a lot of teenagers driving while texting and not paying attention. Michigan roads are fuckin terrible.
There's a lot more I could add, but that's the stuff that came out on top of my head. Of course it's easy to be very critical of another country when it's different from your own, but I've tried to stay pretty impartial and honest. Most of my stay was in the northern part of states... mainly Michigan, Ohio and New York. I thought it would be interesting for some of you people to hear a foreigners experience of america that is not based on what they see or hear on the television. I
worked and lived there for 4 months. Successfully I might add.
In the end you realize we're all humans and whatever difference there might be in culture or political climate it's not what's important. I made a lot of good friends over there and had a blast for sure.
