I was thinking about that when I was dropping my 6 year old off at some hobbies earlier - it’s pretty much expected to have learned how to ride a bicycle before starting school, and it massively expands the area you can go to by yourself. When she went to school by bicycle she can easily make a detour via a shop to spend some pocket money before coming home, while by foot that’d be rather time consuming.
Quite a lot of friends from outside of Europe either can’t ride a bicycle, or were learning it as adult after moving here, though.
edit: the high number of replies mentioning “swimming” made me realize that I had that filed as a basic skill pretty much everybody has - probably due to swimming lessons being a mandatory part of school education here.
Bottles. It’s similar in The Netherlands, it’s a bit of a sport to open beer bottles with anything and everything, except dedicated bottle openers. Quite popular are Bic lighters, other beer bottles and the edges of tables.
Beer cans usually have pull tabs, they’re just soda cans with a different brand on it.
I’m American and this is how it was when I was in college and went to parties. I rarely, if ever opened a beer bottle with a bottle opener. My bic lighter was the most common tool, but as you said, learning how to improvise with whatever was on hand was key. It was a proud day when I found that the trucks on my longboard had a sweet spot for cracking beers open
A bottle. As some Dutch person said in another comment, cigarette lighters, edges of tables and another bottle are popular options. Please don’t use your teeth. I have a nice, rounded tooth that I used to use for opening beers when I was younger - I was lucky I didn’t damage it more.
