Are the people in your country more social and open, or shy and closed off?

It recently hit me that Belgians take their personal space WAY too seriously. We're always afraid about coming off as rude to other people and as such, never seem to be willing to have a conversation with strangers. There are a few theories as to why this is, but my most predominant one is that Belgians just have a huge temper problem that makes us afraid to in any way evade their privacy. Like, seriously, make a Belgian angry and you'll be scared shitless.

Meanwhile, when I see Italian or Portuguese people, they're always enthusiastic about greeting anyone they pass on the street, they go out drinking more, they have better relationships with their neighbors, and they visit their relatives WAY more often! This is a pattern I also notice within many foreigners in school. Greeks, Romanians, and Danes are incredibly easy to talk to, whereas Hungarians and Ukrainians seem to prefer to be left alone.
