Parents on Cell Phones

I was having lunch in Bryant Park yesterday when I noticed a couple glued to their cell phones at a nearby table while their son, about 8, a false smile frozen on his face, kept singing invented songs offkey and making robotic gestures. At first I thought perhaps he had a disability. Then I saw him banging on the table, tapping his parents on the arm. Without looking away from their phones, they shushed him. I was so sorry for that kid that I could barely eat my Avocado Toast, a favorite. What will he be like as he grows up? Will he continue to have a false persona? Will he have any idea that he has any value? Will his movements always be stiff and joyless? (Sigh.)
