In Finland, many people speak English and Swedish. Finnish and Swedish are the official languages taught in schools, because Finland is an official bilingual country. A considerable proportion of Finns can speak more than two foreign languages. They also travel a lot during holidays, so they are exposed to other cultures.
Many Finns also grew up in libraries. The library is an important part of people's life here. They may do their homework or do their hobbies there. This is a safe environment. Perhaps the best example in practice is the OodiHelsinki Central Library, which opened in 20 18. The bright open space is a hodgepodge of many different areas, from books and desks to recording studios and sewing stations. It was built into a working space and living room for Helsinki people. When I went there, it was crowded with people who liked this area. Jonathan, a taxi driver, said that this is a good place to support the family. He explained that he never worried when his children rode bicycles nearby alone.
Of course, there will be a certain degree of crime in any city, but even in Helsinki, the capital, there is no major public security problem.
