Put the phone face down for one meal and count how many things you would have missed.

The cost of a phone at the table is invisible by design, because what it takes from you is the things that never got noticed. You cannot miss a conversation you did not know was starting. The only way to see the price is to run the meal without it once and count what turns up.

So try one dinner, face down, and keep a mental tally. A joke, a story about somebody at work, the fact that your sister has been quiet all week. Whatever the number is, that was the nightly cost the whole time, and nothing on the screen will have moved.
