You can be in the same room with your whole family and still be in six different places.

Physical presence is the cheapest part of being together and it is the part everyone counts. A room can hold several people each attending to something else, and that can continue for years while everyone assumes the closeness is intact. Nobody decides for this to happen, it accumulates.

Try one thing this week that requires the same attention from everyone, a meal without screens, a walk, a task done together. Keep it short enough that it does not feel like an intervention. Shared attention is what makes a room a room, and someone usually has to arrange it.
