Im danish, and out of 10 people 1 is perhaps a little annoyed at something, mostly the current refugee/migrant crisis. But the danish people is a very private people, which is probably why outlanders seems to think we are a sour and pissed off people.
all my friends and I have quite a bunch, are happy and going strong 90% of the time, some of t hem have good jobs, some dont, but they are still happy with how they live.
But again, we are kinda withdrawn and private, we like to have our "spheres" of space between us and the other guy/gal when walking on the street, we also dont talk to complete strangers in the train, bus or at the movies.
When we do talk to strangers, we are usually drunk ;-)
