It's a new spot for the Norges Posten, the Postal Service of Norway.
Let's, for now, not think about the possible future cohabitation problems of these two love birds, and just enjoy the very creative romantic gesture.
Also, let's hope thousands of other Norwegian young men/women don't copy this stunt, and then are subsequently rejected by their girlfriends/boyfriends. Though that will equal tons of new business for the Postal Service.
