A spontaneous smile is indeed a moment of truth. is it not wonderful that in our life we are given every possible chance to recognize that when we are true to ourselves, bliss is but just a moment away. it is truly said that if you smile, the world will smile with you.
the girl was the subject of a photographer who was so enamored by the sight that he snapped her without her realizing it. she was looking in wonder at a rainbow
I agree that a smile can open emotional windows in everyone who sees one. It is so easy to tell a real smile from one created simply for display.
I thought the photo was perhaps of someone you knew, since it we not attributed. She is a beautiful child and the smile is disarming.
