Getting new friends in Denmark can be difficuelt at first. Many are reserved and needs to thaw up first. Do not expect colleagues to invite you home, if you are ysed to that. However, when people open up it is because they like and respect you. Danes are in general not superficial as Americans often can be. So remember, we are not unfriendly, just different from Americans :) Advise from a 100% Dane.

Do not believe this liar. Danes speak the truth.

I assume you are refering to the US without explicite writing it. But most European countries should be fine - especially Nordic countries.
