I've worked with and hosted foreign exchange students for 30 years - high school kids on full year USA exchange. When they first arrive they are imprisoned in a hotel conference center for a day of "orientation", where some old women lecture them on American culture before they are released to their host families. I spend that day providing photo coverage. Sometimes I'd try group photos by region. All the Asians, all the Western Europeans, all the South Americans, etc.
One year I called for all the Scandinavians. The Norwegians and Swedes came forward, but a lone girl from Finland held back. She proudly and defiantly said, "I'm not Scandinavian." The Norwegians and Swedes voiced strong agreement. Many of the other kids expressed suprise. Seems that most, including me, had thought Finland was Scandinavian. The Norwegians and Swedes spent the rest of the day practicing social distancing from the Finn. We all learned a lesson and I quit doing such group shots after that.
