Kindness over everything.
Reading those three words on the shirt of a little girl while waiting in line at my local convenience store, I was so overcome I almost didn't say anything to the adult standing by her side. I was sincerely worried that if I spoke at that moment, I would inexplicably break down in public, running the risk of both scaring the girl and embarrassing myself.
But, following a few deep breaths, I told the adult how moved I was by the simple message that shirt conveyed. The little girl heard me and smiled. And I made my getaway before melting down.
Imagine the world we could live in if each of us took those three words to heart even for just a few hours every day.
