When sadness comes, then that's when we need someone who will wipe out the sadness with laughter.
What is the meaning of happiness if there is no sadness behind it.
Do not be weak and despair of sadness. There are many others who are also the same story with you.
Everyone has the right to feel good about what he has and everyone has a right to feel sorry for what is missing.
The most precious thing in the world is happiness and the heartbreaking thing in the world is sadness. Therefore be happy and do not be sad.
