Thank you for taking me home

Thank you for taking me home’: Air passenger leaves handwritten letter for pilots in bid to ‘spread compassion’ following Germanwings tragedy
Chances are you’ve seen this letter circulating and making the rounds across plenty of websites. It’s such a simple act of kindness, but it’s left a permanent mark on the heart and soul of millions of people around.  The author (Bethanie) wrote this with no intention other than to let people know she appreciated them.  She wrote a letter from her heart, letting them know they matter and what they do matters.  She was kind. 
How can we inspire kindness in our lives and those we know?
