I think sharing a smile with a stranger is something most of us have been conditioned out of doing.
When we are little we had to watch out for the Man offering us candy.
As we grew older, we learned to be scared of looking at a stranger because they were probably crazy, a molester, a rapist, or a general purpose maniac.
As we get even older, we see robbers and murderers in every other person, even our neighbors.
We have been conditioned to fear strangers almost since we were old enough to talk.
Our world would be a much friendlier place, if we realize we do not need to live a fear based life.
Once each day smile at a stranger like you mean it, and say, “Good day”. You might even save someone with your smile. More has been done with less.
