I remember vividly a phone call from my son. It was at a time of war and he was in the fight. I was not allowed to know where he was or what his mission was designed to accomplish.
Cell phone use and communication via email were forbidden. He had been “off the grid” for quite some time, yet firmly situated in my thoughts and prayers. Finally, my phone rang one morning and I heard his voice. His unit was, at last, given one calling card to be used among them to call home.
