Non-Swede who lived in Sweden basically all of 2020 here.
We basically self isolated most of the year and only did grocery shopping with masks and keeping distance but a lot of people really did not care about social distancing or masks. My wife and I were often very uncomfortable being out of the house and really did not like the relaxed guidelines. We commuted a lot to Denmark and the contrast was huge. We felt so much safer and comfortable being out shopping in Denmark compared to Sweden.
We moved to Denmark start 2021 and has been back and forth between the two countries monthly and there’s still a big difference in behavior.
