This is a small world

I've heard and used that saying so many times,  when I run into a friend while 100's of miles from home, or I meet someone new and find that they are married to my 3rd cousin on your grandmother's side of the family, or ......well you know what I mean.   But sitting in the airport the other day, just watching all the people pass.... made it clear to me that there are millions and millions of people.... living a life, wanting the basic things is life we all should have,  food, shelter, love and compassion.  I sat there and watched, and made eye contact and smiled and even though everyone was in a rush to catch a flight or get their baggage, they all smiled back.
