Being a very friendly person, I smile at or say hello to nearly everyone I come into contact with. To me, it's a matter of common courtesy. Having no hidden agenda, I'm amazed at the strange looks I get when just trying to be cordial. People scurry about paying no attention to the world around them. Not to say that my focus is always unselfish but, I make it a point to acknowledge those around me. A smile or a kind word can make a difference in someone's day, plus it opens my heart and mind. I've been told that a smile is contagious. How sad it is that we've grown so cynical that, we question the sincerity of the person trying to be polite.
