Related, my kids make grumpy faces when I tell them to turn off "background" Netflix or YouTube while they're doing their homework.
Semi related, my wife's friend came over and it was suggested we watch a film. "Aliens" was chosen as the friend and my wife hadn't seen it before. I put it on, they started chatting. When they started chatting I paused the film. They stopped chatting and asked what was up. I said that you started chatting so I figured you weren't watching the film, and I was actually trying to watch it. They promised to stop chatting. I played the film, they started chatting again after a short pause. We went through the pause/explain/promise cycle again and I played the film. They both promptly fell asleep.
