Say Hello on World Hello Day

Today, and November 21st annually, is World Hello Day.  It was established in the fall of 1973 after Egypt and Israel came close to conflict (the Yom Kippur War). 

I love the idea behind this commemorate day, which encourages everyone to simply say "hello" to 10 people. But why limit it, why not just say hello to everyone you encounter today. The idea is that by greeting people we send a message to world leaders urging dialogue over conflict.

It was proposed and promoted by Dr. Brian McCormack and Michael McCormack of Arizona State University in the United States. The activity has now spread to 180 countries.
