Do you have children?
This is one of those things where when you're talking about it or thinking about it, it's common sense. Of course you're not going to let them watch TV! Or Youtube!
But then when you have a kid who is _just_ not stopping to cry, and you happen to be working from home this one day, and can't afford a babysitter or daycare, and you're tired and terribly sleep-deprived, you ... just resign to it, you give them your smartphone and off they merrily go and you're a little bit of a headache free, for now.
