When you work in a Danish office, you'll often find yourself invited to impromptu in-office social events with your Danish colleagues. Somebody's birthday, someone's having a baby, somebody has been with the company for 10 years, someone is going on vacation the next day. And they almost all involve cake.

Cake is very important in Denmark. Cake builds bridges. Cake makes friends. And when there's cake on offer, as a foreigner, it's a good idea to show up and accept it.

When I first started working in a Danish office, I made a big mistake. I said no to cake.
