There's a saying "If you see something, say something." While some people might want to avoid the trouble of getting into something sketchy, others just can't stay silent when they see bad things happen. That can be especially true if it's happening to a person you know.
In the U.S., emergency call centers handle an average of 600,000 calls a day and over 240 million calls per year. In their own right, Child Protective Services receive over four million referrals about neglected children a year.
But it's never easy to make the call. The folks who shared these stories could probably tell you that. The experiences come to you from an online thread where someone asked: "People who have called CPS or the police on a friend, what made you do it?" Some of these stories have good endings, others not so much, but don't let that stop you from believing that sometimes one call can change someone's life.
