There are tons of poeple who say “IT COULD NEVER HAPPEN TO ME!!!” for various situations (kidnapping, car accidents, etc). Guess what happened next?
Sometimes, “it” happens. And no matter how careful one thinks they are, no matter how much double, triple, and quadruple checking is done, there is always a chance that a really big “OOPS!” could occur.
All you can do is pray and say “There but for the Grace of the Lord.”
But those are things that are out of our control.
You have control of what you do to your kids. It was in the parents' control to make sure this did not happen.
