You have to put your hand up when the bus is coming or it doesn't stop (Ireland). This is because multiple routes service the same stops, so it wont stop by default.
This is a pretty fun thing to learn the hard way when you need to be somewhere important and you stand there doe eyed when the bus you made sure you were there for on time barrels by you in the rain
Also, to stop, you need to press the stop button in the bus. In my country (Lithuania) all buses had these stop buttons, but they were never used. Took me a bit to understand, that people actually use them here.
Mysteriously appearing mosquito bites, even if there seems to be no mosquitoes around.
That's in Taiwan. They have fruit fly looking mfs, which make no sound and are almost invisible, however their bites are as painful as mosquitos. Pain kicks in after some time, so you can almost never tell.
Oh don't worry, you're not alone. Me and my wife were convinced we had bed bugs first 3 months living here. Now you'll know what to prepare for next time!
That eating street food can get you sick. It's kind of funny. I try to tell people that Street food and small restaurants are not well regulated and might be not hygienic but that goes right over their heads because it's unfathomable where they're from.
Could apply to most countries outside of Europe and North America. I personally know this is true at least in Egypt, India, Bangladesh, Sri Lanka, Nepal, Thailand, Indonesia and Cambodia.
That we don't move from one place to another on a donkey, and that we don't wear sombreros.
Being more serious, the thing they really get surprised, is that global media (specially from the US) depict us as a narco state. Life here is secure, people is friendly, and if you don't mess with the bad guys, you'll be fine 95% of the time. Just use common sense as you do while you visit any country in the world and you'll be fine.
I'm gonna say, school shootings, violent cops, homophobia and trans phobia. I didn't forget racism. Racism is still a huge problem, it just doesn't confuse people as much
We somehow keep electing cavemen into office. One actually became president in 2016, despite his "pussy grabbing", baldness and rudimentary grasp on the local dialect.
