Attention is the clearest thing you can give anybody, and a phone on the table quietly announces that something else might win. Nobody needs a speech about it. People read where your eyes go and draw their conclusions without ever mentioning it.

At one meal this week, put your phone in your bag before you sit down, not face down beside your plate. Notice what your family says in the gaps you usually fill with a screen. If someone comments, you do not have to explain; just do it again tomorrow.
