Power of a smile

I can't embed this favorite video of mine, but here is a link.

It is a song by the group, Casting Crowns. It reminds me of the power of a smile or a simple hello. Sometimes a person just needs you to see them. We humans can get caught up in living our lives, dealing with our problems and stop seeing those around us. I try to keep this song in my playlist as a reminder to not let that happen.
