The friend who notices your new glasses before you say a word is paying attention to you. Keep that one close.

Noticing costs attention, and attention is the one thing nobody can fake at scale. Somebody who spots a small change before you mention it has been looking at you rather than at themselves while you talk, and that habit shows up again later, when the change is something harder than glasses. It is a dependable signal of who will be around for the serious stuff.

Keep track of who those people are, then be one of them. Say the thing you noticed out loud. That is how people learn they are being cared for.
