The best pair in the world is smile and cry. They won't meet each other at a time. If they meet, that is the best moment in your life.
“Don't cry because it's over, smile because it happened.”~ Dr. Seuss
“I was smiling yesterday,I am smiling today and I will smile tomorrow.Simply because life is too short to cry for anything.” ~ Santosh Kalwar
“Crying is all right in its way while it lasts. But you have to stop sooner or later, and then you still have to decide what to do.” ~ C.S. Lewis
