The Swedes, whose twinkling lights I can see just across the Øresund strait this evening, have long flocked to their southern neighbor to let their hair down and sample what is, from their perspective, the Danes’ louche, fun-loving lifestyle. (Younger Danes, in turn, head for Berlin to get their jollies.) At the end of the evening a group of us go, giggling, to the beach, disrobe, and tiptoe into the waters. It is something I have struggled to adjust to, but nudity is no biggie here and at least by now it is dark.
