Teacher explains why she kept a disconnected, 'old school landline phone' mounted to her classroom wall

For one former preschool teacher, whose classroom had been described as a spa, calm is the order of each day.

Here’s how it works: When Caylee Carullo, who taught preschool in Denver, Colorado, for seven years would observe a student engaging in positive behavior, she’d pick up the phone. "I pick up the phone and report a child’s good behavior," Carullo wrote in a now-viral Facebook post. "Good behavior only!"  "But I don’t call mom or dad …I call Batman or Minnie Mouse or the Paw Patrol."
