You found something you think it was lost forever, maybe a 100 dollar bill in a pocket, or a "I love you" note, or maybe you read an ad that reminded you of your childhood, there are so many things that can take us away a smile, a cute cat that you meet and purrs, the sunny day that brings you every morning. but I especially believe that you smile because you decided to do it, you decided to be happy, and you want to share it with us, happiness is a choice.
