Before taking Swedish violin lessons, you need to make sure your teacher isn't secretly Näcken. Know the warning signs:
Are they constantly at least slightly damp for no discernable reason?
Do they demand payments in snuff and akvavit?
Did you meet them on an old bridge, the kind they don't make anymore?
Have you caught them in an unguarded moment playing their violin next to a stream while wearing little to no clothes?
Are they sometimes a horse?
If you answered yes to any of these questions, they may be Näcken. Be very careful about playing any song they teach you, once you start playing, it's not a guarantee you'll be able to stop!
