The rarest thing you can give someone is your full attention with your phone face down.
GRATITUDE
GRATITUDE
Attention has become the scarce resource, and everyone can feel the difference between being listened to and being processed. A phone on the table does not have to buzz to do its work, since its presence tells the other person they are competing. Undivided time is rare enough that receiving it registers as being valued.
Try one conversation this week where the phone is out of sight rather than face down in your hand. Ask a second question instead of answering with your own story. Twenty minutes given that way is remembered longer than an hour spent half present.
Who deserves a conversation with your phone out of reach?
Free, with nothing to buy inside it.
