Smile because you woke up this morning, you are alive and you have another day to take on the world. Smile because you can see the sunshine in all its glory and also see it set at the end of the day.
We've all felt hurt, betrayed, misjudged, cheated, insulted, taken for granted or abused at a point in our lives. It sucks when people we trust hurt us, believe me I know, I've been there and it has made me angry and sometimes very sad. Our reactions to being wronged are different.
