You are where your attention is
This line has stuck with me since first reading Andrew Sullivan’s excellent article on distraction last week:
You are where your attention is. If you’re watching a football game with your son while also texting a friend, you’re not fully with your child — and he knows it. Truly being with another person means being experientially with them, picking up countless tiny signals from the eyes and voice and body language and context, and reacting, often unconsciously, to every nuance. These are our deepest social skills, which have been honed through the aeons. They are what make us distinctively human.
