When you walk with wholeness and humility, there are those who will hold your gaze for just a moment longer than you’d expect. There are also those who will avert it and disengage immediately.
Those who hold it are those who recognize you, even if only for that slightly longer than usual moment.
Those who avert your gaze are those who need your light most.
What you do with that information is up to you. I find that a smile works well in either case.
