NUUK, Greenland—The posters are plastered on school walls and at bus stops across Greenland's capital city. The message, aimed at teenagers, is a direct plea to use a special hot line: "The call is free. No one is alone. Don't be alone with your dark thoughts. Call."
If you know anything about Greenland, you know that it is the world's largest island. You know that it is the least densely populated country on the planet. You might even know that Richie Cunningham spent two seasons of Happy Days stationed here with the Army.
