Come to Scandinavia if you really want to see an individualistic culture. Striking up a single conversation with a stranger is frowned upon. People going to North America always come back saying everyone was so talkative.
Swedish person living in the netherlands for 12 years and i can only agree. Sweden is a emtionally cold country, and even though we have space that looks like it could invite to social behaviour, make no mistake about it, people will assume that you are after something/trying to mug them if you attempt on only being a tad social. I live in Amsterdam now which is a lot more open to chit-chat, but the Dutch live very much for them selves, are so tired of tourists that you really have to speak fluent Dutch to not be cosidered someone they will never see again.
