My doctor said, 'You need to reduce your screen time before bed.' I said, 'Doc, I put my phone face down on the nightstand.' She said, 'And then?' I said, 'And then I stared at the ceiling for forty-five minutes. The ceiling is not a screen. But it's a surface. And I was looking at it. And it was flat. And it was in front of my face. Is that screen time? Is the ceiling a screen? I need you to clarify. I need to know if I'm in violation of your rules by looking at a wall.'
