"Cairo, Egypt: Wearing camouflage clothing.

"I don't know what it is but for some reason, a lot of tourists walk around like they're about to go on some super dangerous, ultra important journey through a jungle. They wear big hiking boots, thermal backpacks, etc. They also wear very camouflagey stuff.""

"I live in Toronto, ON. It’s not too different from any typical North American city but there are some particulars:

1. Pronouncing it “To-ron-toe” instead of “Tuh-ronno”: Locals always drop the second T. It’s such a part of our identity that Canadians from other parts of the country, even if they’ve lived here for years, refuse to drop the second T. It’s stems from the love-hate relationship the rest of Canada has with this city.

2. Calling the Subway lines by number or colour: They used to be unnumbered, and we only have a measly four lines, so we would refer to Line 1 as “the Yonge line”, Line 2 as “the Bloor-Danforth line”, Line 3 as “the Scarborough line” or “Scarborough LRT”, and Line 4 as “the Sheppard Line”.

3. Standing on the left side of the escalator: However, there have been some issues about how the rule of “stand on the right, walk on the left” might be troublesome for accessibility, so this rule might change in the future.

4. Biking on the sidewalk: I know this city has a severe lack of bike lanes but that doesn’t mean you risk the lives of innocent pedestrians.

5. Assuming there is only one Chinatown: There are actually two official ones downtown. Prominent Chinese communities also exist in North York, Scarborough, and the Greater Toronto Area. I would argue there is better Chinese food uptown than downtown.

6. Asking how to get to Niagara Falls while in the middle of the downtown core: Niagara Falls is a different city about an hour and a half outside of Toronto. I’m afraid you must be very lost if you want to get there.

7. You don’t immediately shudder when someone mentions the Dufferin bus: Beware the route 29 Dufferin bus. Beware."

"Mexico City: we know you’re a tourist when you start trying to respect road signs and stoplights. If there’s one thing I severely loathe about this city- it’s not the pollution, nor the crowded feeling you get once you get here, nor the un-ending yearn from locals to believe that any foreigner is automatically better qualified for the job- it’s the utter disrespect and indifference for your own life or those of others. Big 6-lane avenue? Let us ignore the bridge and cross underneath it while we zigzag between cars and their scared drivers. Stoplight just turned green? Better cross with my 3 kids behind me while cars honk at me. You want to cross the street now? Ignore the zebra crossing and run almost drunkenly through the street while cars are still circulating (this is almost a national tradition). Both-ways street? Let me park my big-@$$ truck here and not let anyone through. Bike-lane? I, as a cyclist, want to draw the symbol for infinity while getting in the way of other 8 lanes. Subway doors are opening? Better charge like a quarterback and maybe punch my way through before letting anyone from such wagon out. In the midst of this, you see confused tourists being pushed by the locals because we just can’t wait to cross even if the stoplight turned green 2 seconds after. You see people waiting at the zebra crossing wondering why people are crossing all over the avenue. If you see people trying to do things correctly in the vicinity of streets or public transport, they’re most likely tourists. Works the other way around. Once in Vienna I crossed a street following my mexican tradition of doing it wherever and whenever I please (and ignoring the zebra crossing), and a policeman gave me a warning! It was a tired, compassionate one, as in saying ‘you people just don’t know any better, so I’ll let it pass’. I was so embarrassed for me and for my country. I’m trying to be better now."
