You hear about random acts of kindness taking place in Nashville, especially around Christmas. Someone buys coffee for a couple of people at Starbucks, and  generates a kindness chain that lasts for several hours.   If you need ideas on how to be randomly kind year round, check out Spreadtheglow.com.  You can learn about what's going on across the country, and download a card to hand out, so even the hardest heads get the point. 
This group has produced a movie and a magazine, as well.  But you don't need to buy anything to enjoy being kind.
