Watching children in Mexico happily eating crickets like they were popcorn. Also, 4 or 5 year old kids out at 10pm to sell gum.

The only thing that really shocked me in France was how casually people talked about taboo subjects. I mostly had a huge culture shock when I came back from France. Caused me to be pretty depressed for a year.

Dutch here. When we went to Canada, everything was HUGE. Big cars on big roads, big streets and restaurants and malls. I remember driving for what seemed like hours through suburbs, and I just kept thinking, 'surely after the next turn we’re out of the city', but the city just seemed to be endless.

Not mine but in college I had a roommate from Australia who was studying abroad in America. We went out to dinner one night and I got mozzarella sticks. He could not believe we just deep fried cheese and then ate it

America has drive-thru everything! Drive-thru coffee, drive-thru ATM, drive-thru liquor store!

Grocery stores in the US, the amount of food getting wasted has to be insane. And then the reverse culture shock moving back to Europe; [come on] people, talking and being nice to strangers doesn't cost anything.

Witnessing PDA everywhere and frequently in France. I'm from a little conservative Asian country. Here couples rarely do it and when it happens it's just hand holding

I moved from Europe to USA. How Americans idolize their politicians. These are public servants, YOU PAY THEM! your taxes pay them, THEY WORK FOR YOU!

The mid day siesta in Italy where everything is closed for 2 hours. The entire culture is so much different than America's, it was great

Barefoot people EVERYWHERE in New Zealand. In Starbucks, in the mall, on public transit, walking down the street. No shoes, no socks, no [damns] to give.

I know it sounds ridiculous, but my biggest culture shock is 'hugs and kisses.' I grew up in a family that doesn't show love through such means.

My cousin visited me from Nigeria and couldn’t wrap her mind around the fact that we have entire stores here just for pets and pet products. In Nigeria most of the dogs are allowed to just run wild.

How queueing works in China. I’m from the UK, where standing too close to someone or pushing in front of them is basically akin to criminal behaviour.

I'm American and I had never left the country. When I traveled to Japan, I was seeing kids so often travel by themselves and leave their bags in places like at seats when they went to go order food, etc., without a worry of anyone stealing it. It was very surprising but also gave me a sense of safety I have never felt in the US.

When a large Maori man asked to touch noses with me in greeting. The dude looked pissed until I manned up and was the first to touch noses. Then he had one of the best smiles I've ever seen on a mountain of a man. It lit up the entire cultural center.

What is with American toilet stalls having the doors end like two feet away from the ground? Every time I took a [crap] I was half expecting to see someone poke their head under because of how much space there is

When I went to Dominican Republic, my family and I saw a guy literally go behind a bush, put his pants down and take a dump. One of the locals told us that this was a common thing there.

American here and I lived in the Netherlands for a bit. The first time I went to the doctor and he had actually read my entire chart beforehand. Oh, and then the total for my visit was a few euro. That was a pretty big shock too.

Recently moved to the US (9 months ago), and I am still not used to everyone asking me how I am doing. I am from Norway, and if the cashier asked how you are, you'd get embarrassed and wouldn't know how to answer.

Just how late the Spanish eat dinner. Totally respect it, but I was hungry at 6pm and was shocked no restaurant was open to serve at that time.

I grew up in a Southeast Asian country, and moving to a Western country, I realized the stark difference on parenting. It's much more individualistic in Western countries, rather than community-based.

I'm from the Philippines and I've lived for at least a year in the USA and I was so shocked people in the US would... just greet and help strangers out if they needed help? Here in the Philippines if someone you didn’t know greeted you and talked to you out of nowhere, we’d be weirded out.

The sheer amount of nonchalant waste that Americans do took me off guard. They just... leave the faucet running or throw away food if it doesn't look perfect.

I'm a black South African, in my culture a woman doesn't leave the house for about a month after she has a baby. This is to avoid things like infections, bad spirits and so forth for both mother and baby. Also for the first month she doesn't do housework and must focus on the baby so usually family members come to live with them to help out. I was shocked when my English friend's aunt was cleaning the house and going out to shop for groceries a week after she had the baby and she took the baby with her. Not to mention she allowed a stranger to touch the baby which is a big no no in my culture.

So I’m norwegian, but I went to New Zealand for a year. The culture shock for me was how open kiwis talk, and how there’s no such thing as stranger danger. And as a typical norwegian introvert, it took a while to get used to. I’d meet a stranger and they’d be breaking the touching barrier right away and start talking about their cousin’s rash and all their weekend plans. Even bigger shock returning to silent Norway.
