Whenever I did this, I was consistently astounded by how the faces of those people lit up and broke out into a smile. It was almost like a little miracle. Miserable-looking faces suddenly became pictures of happiness just because someone, who they didn’t know, took the trouble to smile at them and greet them.
It seemed to work wonders for so many of them. It clearly made them feel better and I saw, overtime, that it seemed to greatly improve the atmosphere in the whole building.
I am now a firm believer that the simple smile of just one person can help to improve the lives of so many others.
Go on! Give it a try. Create your own little miracle. It will also make you feel better.
