“Americans should be informed of this because it’s very unpleasant...”

"There also seem to be a lot of secondary flags besides the main US flag, which I assume are for states."

"I knew that suing people was a big thing in the US, but I never realized that most of those cringy ads would be on giant billboards.

I suppose that's not a detail that makes its way into a TV series."

"Literally every time I’ve taken a dump in the States, I end up making eye contact with another dude because none of your doors fit properly — it is so odd!"

"I used to drive from Ontario to Michigan. The highway in Canada was just farmland, but the second I crossed the border, there were big, loud billboards everywhere. With all uppercase letters, it felt like they were yelling, 'EAT HERE!' and 'SHOP NOW!'

The portions are huge, and the number of fast-food restaurants in a one-block radius is astounding. Everything just feels so big and loud."

"If you are in uniform, you are on duty, and if you’re on duty, you comport yourself correctly, not like a bunch of lads on a night out, laughing, joking, and speaking loudly."

"An Austrian friend of mine said that Europeans go around an obstacle while Americans trample over it."

"I have a friend who worked for an American cruise ship line and eventually quit because he could not stand how loudly the US passengers spoke. 

Americans should be told this because it's very unpleasant."

"I met a guy who didn't know that England was part of the United Kingdom, and a couple of women who thought that Europe was one country; they were surprised that it's a continent containing multiple countries with many languages, etc. That was totally weird to me."

"Other than that incident, I was surprised by how over-the-top nice people were to me that at one point I was sure they were trying to rob or traffic me. It turned out that they weren’t; they were just that outgoing to tourists."

"I hope Americans know it's not normal to give birth and go back to work: I think they know it, the rest of the world certainly knows it, and yet the US does nothing about it"

"Whether they're on the left or the right, or whether they're religious or atheist, Americans you meet always seem to think that their particular worldview is the only possible answer, whereas most people around the world seem more introspective. Yes, we have people in Canada who are cognitively inflexible, but Americans all seem so self-assured in their own ontology.

And don't get me wrong, they're always friendly, but people ask you questions about the culture and framework of where you are from and stare blankly at you like they don't believe the answer, like their brain can't conceive of a society that is different from the one they exist in."

"I went to a supermarket in Florida that turned out to be a right-wing supermarket, complete with Trump merch and cutouts, but other than that, it was just an expensive, nice grocery store. Key lime pie just next to a cake with the President's face on it, I can chalk that up to just being Florida. 

But I started to wonder how many people were armed, especially since the store was packed too. I probably never was or will be next to so many guns in my life. 

And the one time we went out drinking, one guy had to bring his gun — for drinks. How is this even allowed?"

"For at least the last 40 years, the American economy has treated Americans as disposable goods. Use 'em up until they are burnt out, then abandon them — unless they have money. Yet they will swear they are the best damn country in the world. The 'wealthy ones' think they have won because they have a nice home in a nice neighborhood and can send their kids to private school. They're just living in a gilded cage.

The whole country seems to have put itself into boxes — Republican, Democrat, Boomer, Gen Z, North, South, Black, White, Christian, etc. — until fear and division are all that is left.

Americans were loud, but they were always our friends. I feel like I'm watching my best friend being robbed and beaten, and I can't do a darn thing."

"After explaining I was Australian, many Americans just said, 'Oh, okay,' and realized they weren’t going to get a tip from me."
