The year was 2012. Only 39% of the population had smartphones. Parents weren't allowed to friend their kids on Facebook yet. Amy and Kevin were sweating it out together in an un-air-conditioned college dorm for honors students at Virginia Tech. Amy was there because of her illustrious high school accomplishments.
