Question: I have never been to Scottsdale. Why do the Goth kids consider it to be a miserable place?
Answer: Scottsdale is a well-liked destination for fun; resorts and spas, outdoor activities like hiking and rock climbing, golfing, cultural events, and a bouncy nightlife. It's generally considered an upbeat and convivial place, exactly the sort of environment the gloomy Goth kids would consider to be awful.
