Growing up, the only thing more stressful than discovering I had missed several texts and a call from my mom was losing my phone itself. With the way that she could worry, I figured she had half a mind to call the police by the time I finally answered.
And of course, those situations are doubly stressful for parents, who often feel every minute of those hours of radio silence.
So it's not much of a surprise that somebody would get tired enough of this phenomenon to do something about it as one British dad has.
