Swedish is the main language, but just about everyone here also speaks English. Learning Swedish is challenging because so many Swedish speakers switch to English when they're speaking with English speakers!
Sweden uses the Swedish krona, abbreviated as S.E.K., and pronounced 'crown'. I have yet to actually see any coins or paper money, as Sweden is primarily a cashless society.
Sweden is very proud of its tap water, so most people carry their own water bottles, as water is free and available in most places. Buying one in a store costs around $2.00, although it's uncommon.
I had a chicken shawarma burrito in the multicultural neighborhood of Rinkeby, and I shared an enormous kanelbulle (cinnamon roll) with friends during fika (Swedish coffee break) in Gothenburg.
This week in my Swedish class, I learned a song about the days of the week in Swedish called "Veckosången".
