The Church of Jesus Christ of Latter-day Saints has released a series of videos intended to help keep its missionaries safe out in the scary world.
It makes sense, given that many if not most missionaries are barely out of puberty when they go. They have little worldly experience when it comes to crime, appropriate behavior between sexes, or even making their own beds.
I was 20 years old when called but still emotionally about half that. I knew it, too. Which is why I entered the mission home in Salt Lake City with a massive inferiority complex.
