The ability open a glass bottle with a utensil instead of using a bottle opener.

Swimming. My brother in law is from India and he never learned how to swim due to him growing up in a place with only one extremely dirty river and no other lakes or swimming pools near his family. Apparently no one in his family can swim. He kinda can swim now but it still looks funny. A bit like I must have looked from the outside when I learned to swim - as a six years old. I always found this very odd because the dude is smart, hard working and has a degree but it took years and him becoming a dad to realize that swimming is something pretty much everyone can.

How to order coffee, get what you want and keep the line moving without any needless human interaction.

I'm from Seattle and so many tourists want to chat up the barista. Go to the stripe and sip coffee stand for that. If you are ordering something that requires more than 10 words, use the app or be prepared to get something left off and move on. For the love of choice don't try to chat with some stranger in the line.

How to dress for -30C weather. How to get out if you fall through ice into water.

Don't walk on dark places at night.

Clapping. Spaniards can clap, other people can't. I took me years to figure out what they mean when they say that foreigners can't clap and learn to do it properly.

Paying attention to the weather to know if rain or severe winds are coming. I know people have access to hourly forecasts but locals can just tell when the weather will be bad.

Canoeing. I'm not an outdoorsy guy at all but everytime I see US tourists in a canoe they just spin in circles. It feels like Canadians are just born knowing.
