In the middle of the night, West Virginia father Bert Fulks received a coded text message with only the letter "X" from his teenage son. Immediately, the dad sprung into action, calling his son to tell him that he would be there in five minutes to pick him up. This is what Fulks calls the "X-Plan": A lifeline for teens who want an easy and discreet way to leave any uncomfortable situation. Fulks, a pastor, got the idea when talking to a group of teens in addiction clinics.

"Recently I asked these kids a simple question," he explained. "'How many of you have found yourself in situations where things started happening that you weren't comfortable with, but you stuck around, mainly because you felt like you didn't have a way out?' They all raised their hands."

The father-of-three decided to use that information to create a plan for his own teens in case they ever found themselves in a situation where they were uncomfortable. He wrote about the plan on his website, and now, he is receiving national attention, as parents from all over are adopting his advice.

"Let's say that my youngest, Danny, gets dropped off at a party," wrote Fulks. "If anything about the situation makes him uncomfortable, all he has to do is text the letter 'X' to any of us (his mother, me, his older brother or sister). The one who receives the text has a very basic script to follow."

Within a few minutes, the person who received the "X" text is to call the person who texted them. In Pastor Fulks' case, that person would be his son, Danny. When Danny answers with a simple "Hello," the dad would say something like, "Danny, something's come up and I have to come get you right now."
