Although you may get the impression in your business dealings that Danes appear to be unfriendly and uncaring, in fact they can be a very warm people who enjoy lengthy conversations and being with friends. They are especially at ease at home and in other social settings;
Once you are introduced to a Dane, it is likely that you will have an instant friend. Safe topics to discuss are Danish culture, current events, and your home state or town;
It is considered rude to get too friendly with someone with whom you have only a casual acquaintance and to ask personal questions about him or her. This includes anything about the person's private life [such as questions or comments about religion, income, or family]. Allow your new Danish acquaintance to set the tone of the conversation by choosing the topics of discussion;
Many people are flattered by compliments about how they look or clothing they're wearing, but this is not the case with Danes. Danes consider compliments to be inappropriate;
Traditional Danish culture is always a safe topic: showing an interest in anything Danish--from Danish furniture design to Hans Christian Andersen and Legos--is much appreciated;
Again, make the effort to avoid discussing controversial subjects and financial, personal, or family issues.
