Last week, my husband, daughter, and I were at our weekly family holiday, French Fryday, when my preschooler Satya asked for my phone. I've been known to be a little militant when it comes to screens, so I was reluctant to offer it up and annoyed she'd asked at all. "Why do you need it?" I asked. She knew the rules! "I want to take a picture of your hair," she replied. "It's beautiful." Swipe, snap, cry. I did my best not to sob into the ketchup, but that little lady stuck a nerve, as she often does.
